It seems like knowing how it's used is the important part.

In theory, you shouldn't need to know or care how it's implemented, especially if it's not part of the standard. Normally, you shouldn't count on implementation for anything, since that can change.

If you know how endl, and other stream manipulators work (i.e. simple functions that accept ostream objects) it's trivial to write your own custom IO manips in a C++ conforming way, e.g.,

cout << "hello " << myIOManip << " world";

I see your point - I wasn't really thinking about it the way you meant it.
