Ok, that answers that objection. In that case I'd not be opposed to .
being allowed *provided*:

- Portage explicitly enforces it not being allowed anywhere else,
  including in profiles that aren't marked as eapi 4

- The . isn't legal as the first character in a flag name. (Paludis has
  been using [.foo=bar] and the like in user eapi contexts to allow
  fancy queries on metadata. It would be a shame to have to change
  that syntax just for some hypothetical possible use of . in use flag
  names that looks really really weird anyway.)

Or in EAPI 4 for that matter, going by the current state of GLEPs and
PMS...
