This thread is in the SAYC and 2/1 forum, so the presumption is a strong NT. Is it really sensible, in such a context, to require extra values for a 2NT rebid? The problems mentioned in this thread would seem to apply to an awful lot of weak NT hands opened 1M.

"Some people" did not include me. Some people don't open 1NT with a 5cM.

Very close to our auction. Exact up to 3D; then, 3H-3S-3NT(Spade partial).
At this point, 4C by South clears everything up for North --who heretofor had been cooperating with a NT probe. North now knows that South was, in fact, making real cues for slam and is inviting a club slam. They both know that North has a sub NT opening with a wasted quack in spades. North is on the weak side for his opening bid, with only 3 clubs; and he declines slam.
1H-2C
3C-3D
3H-3S
3N-4C
5C
With an expected spade lead, a club contract seems better than 3NT. The better 3NT looks for overtricks, the better 6C looks; so we are back to very little blame for the OP's less informed blast to 6C.

Still, "those people" (not including aguahombre), might consider rebidding 2NT with a weak NT and have lots of bids available for stronger hands. Especially if they are playing SAYC and not 2/1 GF -- now they will have the opportunity to play 2NT instead of being forced higher.
Does anyone know of any real or perceived advantages to the other approach?

The 1H opening and a 2/1 GF response allows for 2 ways for Opener to rebid 2NT-- with "extras" or a minimum ( via a relay system ):
1H - 2C/2D GF
2NT = extras and no 4s
whereas:
1H - 2C/2D GF
2H! ( announces a minimum and maybe 4s ) - 2S! ( asks )
2NT = minimum and no 4s
- - - - - - - - - - - - - - - - - - - -
And when Opener has 4s:
1H - 2C/2D GF
2S = extras w/4s
whereas:
1H - 2C/2D GF
2H!(minimum) - 2S! ( asks)
?? ( anything other than 2NT shows 4s):
the 3-level replies (3C/3D, etc ) can be patterned after the Flannery Convention

the ATB is simple - the players had a different meaning for the 3C
bid, if it can be based on a 3 carder with min val., than obv. the 4NT
bid is ..., if 3C promises more, than the 3C bid is ...
Should be in your system notes.
With kind regards

PS: Assuming SAYC, I think opener should bid 2NT, showing a bal.
hand with 12-14, if 2NT showes more, than opener should bid 2H,
personl I believe 3C should show 5-4.

1H-2C
2N-3D
4C-4H
5C
About the most reasonable sequence I can find.
