Give me a list of all the libraries you work with that don't have some sort of "okay but not that bit" rule in the business logic, or "all of those function are f(src, dst) but the one you use most is f(dst,src) and we can't change it now".

I bet it's a very short list.

Really we need to scrap every piece of software ever written and start again from scratch with all these weirdities written down so we don't do it again, but we never will.
