Looking more closely, it’s actually possible even now to create a
profile with the exact same entry twice:

--8<---------------cut here---------------start------------->8---
$ guix package -p foo -i gnutls gnutls

Weird, but no big deal since they are really the same entry.

(What’s *not* permitted is installing several “gnutls” packages having a
different store file name.  See ‘check-for-collisions’ in (guix
profiles).)

What should we do?  Status quo?  Throwing a ‘delete-duplicates’ call?
Let’s have a poll!  ;-)
