Are we sure that this thing really belongs in the profile, rather than
something that's defined in ebuilds? Or maybe we should have both?

If ebuild devs are forced to use the profile for this, then that global
variable could see a lot of growth in the long-term. OTOH, if it's
defined at the ebuild level, then it keeps the info more encapsulated,
and that may be better particularly for overlay ebuilds.
