The intention is to have the foreign distro experience resemble Guix
System more, esp. for newbee users.  If you have a code base that uses
Guix modules and comes with a guix.scm, running "guix shell" doesn't
work for them.  Unless, maybe, you add "guix" to the package's
native-inputs -- yuck.

They'd have to probably do something guix time-machine --channel=xxx to
get access to guix modules.  That, or source a script that set the
environment variables, which is what we let them do currently.  I was
guessing "everyone" is probably fighting with this, so finally decided
to upstream it :)

If there's a better/easier solution for this, I'm all ears!

Greetings,
Janneke
