At the very least a sanity test to know which sorts of issues we'll hit
with these would be valuable. However, I believe our policy is N-1, and
not N+1,N,N-1, so supporting not-yet released versions isn't something I
think we should spend too much time on. Minor fixes to support these
post release seem like good candidates for a point release.

I personally do not upgrade my primary development machine to
pre-release distributions because I don't want those issues to derail me
from working on features. However, I could certainly kick off VMs
running whatever and set them building on one of our larger servers.

Some sort of distro links for schedule page would be great. If people
want to share that they are testing the pre-release distros, that would
be useful, but we need to find a way to keep it concise and not into a
"getting it to work on XYZ" forum - although that would be useful a
separate page per distro.
