If the foreign distro has /etc/profile.d/*guix.sh installed, as
implemented in the binary guix-install.sh script and also implemented in
the Debian packaging, manually adding this is also arguably not
necessary, unless they are using a shell that does not respect
/etc/profile.d ... which, to my knowledge, is no different from Guix
System really.

There is also the issue of logging out and back in again (or manually
adding the variables for one session), but that seems a little
tangential, and again, is no different for Guix System than on foreign
distros.

live well,
