So the interpreter would somehow have to determine where what profile
it’s in (if any), like ‘current-profile’ in (guix describe) does?

Note that python would still have to run even when it’s not running from
a profile.

I agree… except for using the argument of there being a precedent,
because these were not solutions we were particularly proud of I think.
