I don't have a policy. We discussed it a bit at maintainer summit, that
basically boiled down to stuff should get removed when it is not used
much and/or is causing undue maintenance burden - both of which are
fairly arbitrary criteria.

My feeling is spufs is not causing anyone much work, it does get hit by
some VFS updates but it's just one of many many filesystems, so the
incremental overhead is pretty small I think - though VFS people may
disagree :)

I still have a working IBM QS22, and Geoff is still maintaining PS3,
celleb is gone.

Basically we're keeping it around in case people are still using it on
their PS3s. I don't know how we gauge how many people that is without
removing support and seeing who is annoyed. But even if we did that a
lot of folks will probably not notice for months to years, and when they
do notice they'll just bin their PS3s rather than telling us.

But maybe Geoff has a better feel for how many people (other than him)
are still running upstream on PS3s.
