Given that's how most of the older moderate players around here play (minor on 4432, no checkback), I think almost all of them would invite with 3♥, because there's no other sensible option. If you do play checkback, then pass is pretty automatic - oddly enough a strong tournament partnership had an almost identical sequence at the club on Tuesday evening, and missed game because responder bid 2♥ rather than 2♣ checkback.
I wondered about 2N if partner's theoretically denied spades -3♥-4♥, absolutely hate 3♥, used to play that as unequivocally 6+♥ and a choice between 3/4♥ taking 3N out of the picture. But they have given themselves an issue by denying a spade suit the way they play, imagine if N was 4243, 3♥ would not be a thing of beauty.
