Well, as I said on IRC, that sounds like a wonderful idea, thanks.

Just that most of it will require EAPI 5 for := dep on python-exec. For
EAPI 4 packages (namely: snakeoil), we can just use python-exec:0 for
now and switch at a later time.

Remaining case is how to handle the packages which rely on specific
kind of wrapping. I guess we can make them explicitly pull in
python-exec:0, plus add some switch to control the used version
or use EAPI=4 for them.

I will try to implement that on yet another branch of my
gx86-working-tree.
