I agree up to a point. It is a kind of tug-o-war, and yes, the weight of each side plays an important role there.

Nevertheless, even in projects where my services are talking to something that's bigger, I will, at the very least ask "why cant it be RFC compliant? is there a reason?". And without blowing my own horn overly much, but quite a few systems larger than mine have changed because someone asked that question.
