Although there is an EXTRA-PACKAGES field for Guix packages (I use it,
e.g., for font packages) and a CONFIGURED-PACKAGES field specifically
for installing Emacs packages, I do like the idea of having a separate
Emacs profile, or even a separate profile for each Emacs server.

Part of me wanted to find a way to do that more "properly", with some
sort of lower-level `home-emacs-environment-service-type' that sets up
the profiles (hopefully in a more orthodox way), etc.  But that turned
out to be even more hacky in the end.

Looking at the Emacs build system modules, I'm not sure exactly how
building separate profiles would allow native-comp without transforming
the package inputs.  Isn't the build system basically hard-coded to use
`emacs-minimal' for building Emacs packages (i.e., unless we manually
transform the package inputs)?

At the very least, I'd like to set things up the best I can for this,
even if I end up leaving it to people with more expertise to implement.

Thanks (!
