Looking at [2], it appears the SELinux work for Arch is much further
along than it once was.

I'd suggest that someone maintains an unofficial repo with all the
packages required to set this up to prove the work required for
continual maintenance of this has been done.  Then requests could be
made to (e.g.) add support to the kernel, providing full details of what
is required and if it has any effect on those not using SELinux.
