Is N entitled to an alert, yes, I also play 2N as GF not necessarily balanced and we alert it and explain it as such if asked.
Is N entitled to any redress, no, serious error, W told him by his 4♠ bid/blackwood response that partner has stiff Q♠.
Ho, STOP!!!
The 2NT,
which was actually asked and explained, told North that West had hearts. The Blackwood responses were not asked.
You ask North to take an inference from one piece of information from the opponents (that he didn't even have), just in case other information that he had from the opponents might be incorrect. Why are you forcing him to rely on the Blackwood sequence and denying him the right to rely on the explanation of the 2NT bid?
With the explanation that he got, North was 100% correct: Playing the 10 is the 100% sure way to beat the contract, as long as West has a balanced hand, a semibalanced hand or (with the exception of some pretty extreme cases that would certainly also be deemed MI) any hand with at least a singleton heart.
Would I have played the 10? No, I don't think so. I would have relied on the Blackwood response, expecting to get the contract 2 down. And I would have looked incredibly stupid if declarer would have had the queen and inserted the 9 anyway since he got inspired. (What do I know? Maybe declarer happened to see partner's hand when I was busy sorting my cards.) This North would not have looked stupid.
Given the fact that this was an IMP match it cannot be a serious error to make 100% sure that you beat a vulnerable slam. If this would have been a pairs game, I could say that North was giving up on the extra undertrick way too easily. But at IMPs, I cannot blame North for making extra sure that a vulnerable slam is beaten, assuming only that the explanation of the auction is correct.

I want my opponents to leave my table with a smile on their face and without matchpoints on their score card - in that order.
