This is, IMO, a leadership-level problem. You'll always (hopefully) have an engineering manager or staff-level engineer capable of keeping the dev team in check.
I say it's a leadership problem because "partnering with X", "getting Y to market first", and "Z fits our current... strategy" seem to take precedence over what customers really ask for and what engineering is suggesting actually works.
