Actually per PMS you are required to revbump (and therefore require
upgrade on users' side) whenever you change the deps and don't expect
to add a new version soon enough. Otherwise your changes don't get
spread and users end up with never-ending blockers and stuff like that.

Other thing is that Portage explicitly ignores PMS in this matter
and uses dependencies from ebuilds rather than recorded ones. This is
supposedly wrong, supposedly slow but allows us to be lazy.
