3NT is a technical error. There are conventions here that can help responder sorting out what type of raise opener has. If it turns out he has an unbalanced 3 card raise, then it's very likely he has a singleton too, making the hand more playable in spades.
"Technical error" is kindly put. If partner has four spades I want to be in spades, and as you say if it's a three card raise his hand is most likely such that I want to be in spades. Whatever gadgets one could play, we weren't.
My current view is that we want to be in spades, pretty much regardless, and pretty much for the reasons that a number of folks have mentioned. However, I also think that on a three card raise with minimum values, I want to be in 3S not 4S. For example, if one of partner's small clubs is a small diamond, this hand will not be playing so well. Not in spades, not in NT. Maybe 2NT.
My partner was neither a stranger nor a regular partner, our discussions were at the level of "Can we skip Bergen?[I am not a fan], "OK but let's do Stolen", "If we must". As far as I know, if I bid 2NT over 2S he would be allowed to pass with the 3=3=2=5 hand if minimal. Maybe I will stumble in to 8 tricks. With his actual hand he would no doubt have bid a natural 3C and I could get out in 3S. If he had four spades he would show them and then, even if he bids only 3S, I would raise to 4S. Wrong perhaps, but I would.
Perhaps a forcing and shape asking 2NT over 2S would be better, but we were not doing that. What I really needed was a bid that asks if the opponent's clubs are 2-2.
