Except, that is _not_ what it is or has ever been meant to do.

It is meant to provide programmers a portable, potentially-efficient
mechanism for machine-independent device access.  Part of that
includes defining requirements for programmers which are, in fact,
portable and capable of efficiency.

If it does one of the above three things you mention, that's great.
but if it fails at its primary purpose, that's a real failure.

to be honest, I don't have time at this point to think seriously about
it.
