Ehm...
This feels like trivial to me.  The entire prefix branch is designed to
be completely compatible when EPREFIX is "" at configure time.
(Privilege related changes put aside, but they should Portage wise also
be backwards compatible configurable.)

The prefix branch is already "backwards" compatible with normal Portage.
I tested it on a normal Gentoo Linux install once.

Yes.  But the Portage guys don't like to push in our work before it's
accepted by the community (e.g. proper consensus discussion on -dev).
