Which (unless anyone has any objections) leaves the question of how is this
going to get done. 

use.decs would need to be changed, which is easy enough, but then all
the ebuilds affected by this would need modifying. 

So, either package maintainers would have to do this (which does seem
like something that's likely to happen) or 1 person/a few people
would have to change all the relevant ebuilds, which would require a lot
of work (and requires whoever's doing it to work out which options are
applicable to each package).

I think the second way is the only way that this'd actually get done,
but it requires one or more volunteers. (I'd happily do it, but it's not
really possible without being a dev).
