There'll be some autobuilder failures if that's not done.
#3 will surely take time too since it was a hardcoded default before the
0.9.31 removal which made the internal blackfin toolchain never work (it
builds now at least, as far as "work" depends on having someone testing
things, work still remains but it's a start).
It also affects other nommu toolchains like ARM, but it's broken for
other reasons for now.
New packages and bumps might break for avr32 too, we just can't hold on
to old software being buggy and/or having security vulnerabilities just
to keep it running on old bitrot toolchains.

If you want to volunteer continuous amounts of time into getting this
right, then maybe, i'm not the only one deciding here.
I can't get the toolchain to build and everything points to "install
some odd host gcc version" which isn't quite right - things are supposed
to work in many different normal scenarios.
But as Thomas said if the latest kernels don't work that's somewhat of a
bad omen.
