Trying to please everyone is a recipe for bloated difficult to maintain
code, among other problems, IMO.

Including system API headers from within our public library headers is poor
software engineering practice, and except in the most exceptional
circumstances we should avoid it. Beyond immediate problems, there is a long
history of latent problems surfacing when porting such code to new
