 I'll be involved in maintaining oldnet, but there are others (mainly
 robbat2) who want to be able to release new versions of oldnet
 separately from OpenRC, and to look into porting it to systemd.

I don't have a problem with the IUSE="+oldnet" issue if no one else
does, it just seemed sort of backward to me, using a use flag to pull in
something that really isn't a dependency.

But this would mean we can forget about any virtuals.

Yes, I was planning to get with Jorge before this hits stable and figure
out what needs to happen.
