I believe it does. If you try to emerge something that is ~ or has ~ on
one of its deps portage will tell you what you need to unmask to make
the emerge possible.

At that point, I would say it is time to consider dropping the affected
arch to dev or exp.

Dekeywording all reverse dependencies makes me nervous. There could be
other packages that share those reverse dependencies, so I don't think
you want to do that unless you know that no stable package on the arches
in question shares the reverse dependencies. I would rather remove the
older version of the package once the stable req has had arch teams
assigned for 90 days and there has been no update to it or stabilization
of the newer version.
