Portage could remove the old package after compilation

ebuild package-new.ebuild compile
ebuild package-old.ebuild unmerge
ebuild package-new.ebuild install

This would reduce the chances of something bad happening, but not remove
it altogether. So it would have to package up the old files first and
re-install them if the new install failed, more than a little messy IMO.
