Of course, if someone doesn't want their code in the staging tree, I
will not add it, that's just being "nice".

As for what I will not put into staging, right now I'm sticking with
drivers only, no filesystems (people have asked already).  I don't think
we have seen any drivers that I will not put into the staging tree yet.
