To me, the most important aspect of your proposal is having all profiles
in one place (Konrad proposed something similar recently, well, “last
year.”  :-))

Like I wrote then, ‘guix package --list-profiles’ was an attempt at
making it easier to locate profiles, even if they’re not in the same
directory, so that you can easily operate on them.  What Konrad noted is
that this returns all the profiles, including
~/.config/guix/current-kind of profiles, which may be inconvenient.

I’m generally wary of enforcing arbitrary conventions, such as a
specific directory to store all profiles, but at the same time I agree
that this can be convenient, so I’m a bit split!

Also, such a change would need a transition plan: what does ‘-p’ become, etc.
