Mark sysutils/bupstash as unmaintained?

I've been using bupstash for several years, and while it's fairly good,
it's now very clearly unmaintained [1]. For such a critical piece of
software, especially one that has not yet made it to a 1.0 release (and
that has some of the rough edges that implies), that worries me.
Personally I will soon be looking at alternatives.

To avoid other people using this, I wonder if we could/should somehow mark
bupstash as "unmaintained" to nudge people not to start using it (and, if
they are using it, to consider whether they need to move)?
