I was just informed that it is also a possibility to do an EAPI bump
just for these variables, which would mean we can avoid replicating
setting ED and EROOT in ebuilds.

The suggestion was to just introduce EAPI=3 with these variables, and
making everything which is scheduled for current EAPI=3 just EAPI=4.  I
was told we could quite quickly have a Portage in the tree that would
set ED and EROOT for EAPI=3 that way.

Are there any objections to this?  If not, I'd like to put this on the
agenda for the next council meeting.
