This sounds fine (and a good idea), but we may want some indication
in the USE flag description (eh), a QA policy to indicate
it's only for special situations, or some note in the devmanual.

Can see people getting this wrong and trying to use it in ebuilds
which would work otherwise. But maybe the "special" in the USE
description is enough?
