As Gnasher pointed out 2♠ is quite wide ranging and the hand, holding a heart void, will look much better when getting jump raised.
You jump to game, because you think you have more than an invitation. The jump is limited but not weak after a preempt.
What would you do with
♠KJxxxx

♦KQTx
♣AKx
I would certainly not pass when getting raised to 4♠.

4
♠ is a sign off. If I am raising to 4
♠ based on power and I am willing to explore for slam opposite a suitable hand, I bid 3
♥ first on my way to game.
4
♠ could be based on a hand like:
QTxxx
xxx
xxx
xx
It is not too likely given the lack of opponents' bidding over 2
♠, but it is possible.
Your statement that 4
♠ is not weak after a preempt is not correct. It is not weak by agreement, but it shows a desire to play in 4
♠. In other words, it could be weak.
The 2
♠ bid is sound in all cases. What partner bids at his turn is based on common sense. With long spades and a weak hand he will bid game.
Is it possible to miss a good slam if you bid 2
♠ on the hand that you present and partner jumps to 4
♠? Perhaps. But it is too dangerous to move over 4
♠. You could be turning a plus into a minus.
I consider bidding on by the overcaller over partner's jump to 4
♠ to be a breach in partnership discipline. What you are saying is either your overcall of 2
♠ was wrong or partner's jump to 4
♠ was wrong.
