If he pulls it, I won't be sitting J KJxxx Jxx Axx because I'm passing with that hand. With the actual hand we're discussing, I'm content if partner partner sits for 3♠x because it certainly looks like it has at least 2 defensive tricks. The hand has significantly increased in value because of the opponent's bidding.
Opposite the terrible opener you quoted, Q10xx Q KQx KJxxx, with the actual hand held, 3 ♠ may not fare so well.
This smacks of extreme resulting, partner is not bidding over 3
♠ with some hands that will play very well opposite J, KJxxx, Jxx, Axx (xxx, Q10x, KQ, KQxxx is an example). I can't imagine not taking action with a 10 count and a stiff (non K/Q) spade.
If Q10xx, Q, KQx, KJxxx is a terrible opener, you don't open enough, and I think 3
♠ is making an overtrick nearly as often as it's going off opposite that, and it's very unlikely to go more than one off.
