This particular symlink was put there by openrc though, wasn't it?  So
I'd expect that on the whole this should be left for openrc to deal
with or otherwise left to the user...?

it's a bit late for /var/run , but i wonder if, for the next path
migration, there might be some way to account for which packages use
the old path, say, make a list somewhere, and have the ebuilds remove
their atom from that list as they migrate to the new path..  Then once
the list is empty the compatibility symlink could be cleaned up
automatically or the user notified..  Probably this would need to be
handled via an eclass and specific function calls in all relevant
ebuilds, as i doubt there would be a way to do this generically in
portage itself.
