Well, I see no reason not to try.

Well, it actually removes some code that seems completely unnecessary.
To I believe the code would be nicer and simpler if it didn't rely on
the vsnprintf return value at all, or at least used it only as a hint.

There's no need to be insulting. Obviously people are still using it,
and while I don't see them seriously complaining (reporting it seems
very reasonable since the MSDN docs are wrong) that's no reason
to not discuss simple solutions.
And we do support e.g. OS/2, BeOS/Haiku and a lot of other stuff that
I'm sure has fewer users than Win2k (there's a good chance there's
actually fewer Linux users out there than people using a Windows before
