If your opponent plays strictly by a point system, like a computer might, and if the piece is threatened, it might be beneficial to keep the value low to trick the oppont to do something else, while you keep the useless pawn as an obstruction, which could somehow limit your opponent’s future moves.
Well exactly. I can’t think of one. It could only be useful in a situation where having a dead weight in a cell would solve some problem or other, but I’ve no idea how.

It’d be an extreme edge case where not promoting would be useful.
Pawn can’t capture sideways, how would it ever be useful?
Forcing stalemate if you’re super down in material
Maybe if any promotion would lead to a stalemate

Anyway, it’s apparantly not allowed.
