Why is this a problem? The X keyboard handling has undergone a couple
of significant extensions of architecture over the years, and that
involved getting lots of people to agree. Microsoft can just do it.
And I don't see what the problem is, anyway: from a quick look at the
MS keyboard model, one could (as one does with X) process keystrokes
through a userspace library to get the desired effect. The keyboard
driver may only handle a couple of shift states and one dead
character, but an input library can do whatever it likes. No actual
need to extend all the keyboard drivers - it can all be done by
TranslateMessage(), can't it?
