Some of the platform code he's removing is not compiled right now. I
would have liked to make it compile, but I don't care that much (and
they don't either) ..

Oh what a sob story .. They can't claim to maintain msm except for the
parts they don't like that much, thats not how it works. If you
have a technical reason why you think hard to maintain code is
"hard to deal with", please put that forth .

If they want they can start submitting their patches to me, and I can
deal with their "hard to deal with" stuff..

Personally I think splitting mach- stuff isn't very useful or
interesting.. There's just no technical reason for it, for example x86
and x86_64 was a win from my perspective , there's a lot more reason to
keep similar things together than to split things up.

The whole risking regressions, do you have proof of why you think that's
happening ? The inverse seems more likely..
