Instead of providing a “guix profile” command, another option would be
to merge “guix package” and “guix environment” to just “guix
env[ironment]”.  We could finally get rid of “guix environment
--ad-hoc” while we’re at it :)

Not with a simple command, but Guix does keep links to profiles.  Take a
look here:

    /var/guix/gcroots/profiles/per-user/zimoun/

I’m not convinced this would actually be an improvement.  We need to
avoid sub-command inflation.
