IIRC, it called user profile.

/etc/profile on Guix System already contains this:
https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/system.scm?h=092467b3b6#n1085
Unconditionally sourcing it two times is not the best idea (while it
probably will work most of the time, still feels wrong and probably can
cause unexpected issues).

There is a reason why GUIX_PROFILE is set before sourcing profile file.
Its value used to set PATH and similiar variables to
~/path/to/profile/bin instead of /gnu/blabla-profile/bin, so in case of
changing of ~/path/to/profile content/symlink all respective variables
don't require updates.
