Good question, I do not know. But if we allow several packages with the same
name in a profile, I do not see another possibility for "guix package -u"
than my suggestion.

There is also the question of conflicts with identical file names. They are
already there now, but their probability should be higher with identical
package names. Maybe we need to rethink the handling of conflicts also.
