Perhaps it's only tangentially related, but it highlights a point of
contention that I have with Guix Home overall, being that it takes a
few very idiosyncratic "shortcuts", that I don't think make too much
sense in the wider sense of Guix. Consider %profile-directory, for
example. I can't see it anywhere in the code for Guix Home, so I
assume generations are currently littered into the user home. The
specific choice of moving ~/.guix-profile to ~/.guix-home is another.
Assume I only want to use Guix Home for one or two config files, well
nope you can't unless you're willing to move you packages as well or
willing to have a pointless symlink that you didn't ask for.
Don't get me wrong, this is still mostly about managing multiple
profiles with Guix Home, but the way I see it, Guix Home's own profile
management could also be improved.

I struggle to see how my proposal would complicate that other than
adding more jobs to symlink manager (perhaps?). For what it's worth, I
do think that job could be much simplified too by storing the symlinks
in an association list
(("~/path/to/symlink" "/gnu/store/path/to/target") ...),
which could be part of a Guix Home "profile" just like manifest.scm is
part of a normal Guix profile. The activation script would then read
this table, expand "~" (as well as check that it is the first letter i
each of the first paths) and create the symlinks according to spec.
Best of all, it doesn't even matter that much if the target is in the
store, in /var/guix/profiles/per-user, or even another place relative
to ~.
Note that I believe that at the point of writing this file variables
such as $XDG_CONFIG_HOME should already have been resolved relative to
$HOME, with the former being specified in home-configuration or
assuming their usual defaults. YMMV on whether that's actually useful,
one could alternatively allow $XDG_CONFIG_HOME/ etc. as leading
sequences too, though that invites more errors when experimenting with
homeless shelters outside of clean shells.

Sounds dirty.
