Originially purpose was the same - to have services depending on
home-environment record fields (fontconfig depended on symlink-path
field, which was configurable back in the days), later we made
~/.guix-home hardcoded and did other changes to remove all the
dependencies for essential services from home-environment.  Now the
purpose feels somewhat different, because it basically a good list of
default services, but not actually essential.  The only thing, that
still depends on home-environment fields is home-profile-service-type.

Globally, I'm good with the reorganization of essential services, but
let's make another thread for this issue.
