Machines should not limit versions, only providers; distros and local configurations are
the ones supposed to specify versions. Then again, this assumption relies on the
"default" configuration being working, which -- in case of pulseaudio -- it obviously
is not.

Not necessarily. It would be better if we could limit it for armv4(t) and armv5(t),
however we don't have such fine granular overrides, hence we need to blacklist
on machine basis.

We can set preference rules per machine or arch, however the general
consensus is that this is being done in the distro or local conf.

Yes that codifies machine knowledge in distro and may have to be revisited,
but at least it has been our working style until now.
