This is disgusting. 2♣, assuming it is strong, should NEVER be opened on a 4441 hand with less than 22 HCP, and I only do it if I have a really chunky 4-card Major or will rebid 2NT. It is impossible in any casual or semi-serious partnership to show a 4441 via 2♣, and any serious partnership won't even bother with it.
Sorry but you are wrong here. This is a specific convention with conventional follow-ups and it works surprisingly well. 16+ is a little light and usually only mentioned in conjunction with playing a LTC method - it would promise 5 or fewer losers. This is not the same as simply opening 2
♣ with a strong 4441 hand that does not fit elsewhere, which seems to be what you are describing. A write up of one version of this is given
here. My own method (see below) is a version of this.

All I can say is 'Yikes'! I would love to play against anyone who does that.
I agree, at least theoretically. This 2NT opening is not sound but I suspect it would be highly effective against unprepared opponents. Limiting the singleton in some way (only 4441/4414 say) would naturally be trickier.

It's really silly to narrow the 2NT response to just that. You are wasting that bid, and I've never had a problem with making a simple response and then usually jumping to 3NT the next round.
Absolutely. I am not sure who suggested this one but it seems like a poor use of a 2NT response.

Both Roman 2♣ and 2♦ were designed to fill a hole in the Roman system, due to canape I think. Neither bid are that good, and in fact I think it would be better to reverse the bids. In Precision Today, one of the alternative openings they suggest was in fact 2♦ showing 16-24 HCP and any 4441 shape. I was enamored when I first read about it, but quickly realized that 16-20 hands can easily be covered by opening 1♣ and then just bidding the Major, provided you had a decent response structure. It also keeps you lower than the 2♦ opening on those hands. The only hands that create problems are the (21)22+ 4441 hands, and they really don't come up.
I think you are confused with the 2M opening bids in the Roman system which showed 2-suited hands with the major plus clubs. These were indeed created to fill a system hole due to canape. For a modern version of this, see Ben (inquiry)'s system. The Mini-Roman 2m opening is usually used in conjunction with a 1
♦ "either minor" opening these days. Then one of the 2m openings covers 2-suiters (both minors) and the other covers 3-suiters. This ends up being quite an efficient method. Ken (Rexford) (inter alia) is a proponent of this idea.
The stronger version is essentially the origin of the 2
♣ -> 2NT convention above. It is good but basically too expensive to devote an entire opening bid to. hence the idea of combining it into another forcing opening.

The more options you put into Multi 2♦, the weaker you make it in terms of accuracy and destructiveness. Sure, the weak 2♥ and 2♠ will still make up a majority of the hands, but then you have to account for the possibility of that any 4441 hand.
Many jurisdictions do not allow a weak-only Multi so including a strong 4441 hand is quite a good option. It is rare, which is precisely what you want for the strong variant. Your arguments seem to be against including any strong option at all rather than against including a 3-suited hand per se.

Again, this fills a hole in the system. It was expanded to include (34)15 hands and 4405 hands to make it more useful and come up more often.
More than that, it probably does not belong in this list because it only deals with a specific shortage and is not part a general way of handling 3-suiters.

This should have been listed right under the "jump to 2NT", though unlike that suggestion, it filled in a hole at the time. It fell into disuse as well, though if the system is very well designed I'm sure it can work.
It has fallen into disuse through a combination of opponents being more aggressive against strong club auctions, thus making resolution trickier, and the fact that there are alternatives which are simpler and better.

Seems like everyone has their own favourite method for dealing with the 4441 hand pattern.
Here's mine. My 1
♣ opening shows 15+ natural, 15+ balanced, or 18+ any. Polish with a weak NT as someone once put it. Over this, a 1
♦ response is negative and bid with (almost) any non-GF. Now Opener's 1
♠ rebid shows an unbalanced GF or a strong (18+) 3-suiter. This is similar to Chris Ryall's method but somewhat more flexible, since the hands can begin at 2
♣, 2
♦ or 2NT according to Responder's strength. In particular, if Responder advertises a bust it is possible to get out in 2M, while if Responder has a max they can start relaying with 2
♦ (over our 2
♣) providing ample space for slam investigations.
Prior to this, as a junior, I played a reverse Benji version where a 2
♦ opening showed an Acol 2 in any suit or a strong 3-suiter or a very strong balanced hand. That should probably be on the list too.
