Maybe they exist but I haven't worked in a company yet that wouldn't fire an engineer or manager for refusing to implement a feature that some salescritter already sold. One of them made the company money (on paper, sure) while the other is threatening to undo the deal. It's not hard to guess which one the c-suites would send packing first.
oh you agree to do it but you laugh, literally laugh, at their deadline. and you say, you can fire me but that's not going to get your software done on time. in fact it will delay it.
they shut up. it's done when it's done.
I've done this many, many times. Oh you promised it by the end of the week and didn't ask me? lol, that sounds like a YOU problem.
