Look, we can all sit and play C++ compiler. But there's
no point. The implementation language for this project
does not make a distinction, and nobody at this end is
going to make pedantic distinctions. People who use C
libraries have to apply some common sense. That is a
fact (unfortunate perhaps) of the language.

And he did it because it was useful to write it
down somewhere. Don't quibble about where he wrote
it down.

Nobody is painting any corners, and nobody is
obliged to do anything. Chill out.
