I was planning on opening a bug before all of this hit stable to have
releng add gentoo-oldnet to the stages when it does hit stable.

if we keep a dependency for a while, even behind something like
IUSE="+oldnet", when we drop it, people will still be hit if they do
emerge --depclean before they emerge gentoo-oldnet.

Also, (although I don't really care about this much because we tell people
not to do it), folks who set USE="-* foo bar bas" in their make.conf would
get hit immediately with this solution.

Am I missing something? It just seems like this is putting off the
emerge command people will need to run for a while.
