I decided to go one step at a time, and prepared a patch series, which:

1. Adds an explicit connection between home-files-service-type and
symlink-manager by introducing a global constant used by both services.

2. Adds a home-xdg-configuration-files-service-type, which accepts a
list of files for XDG_CONFIG_DIR, `(("mpv/mpv.conf" ,file-like-here))

3. Migrates all (gnu home services) to xdg-configuration-files.

4. Make symlink-manager respect XDG_CONIFG_HOME and
xdg-configuration-files-subdir.

After that patch series is merged we can give a time for users to
migrate their self-made home services to xdg-configuration-files and
after for example 2 weeks, remove special handling of dots for
home-files.
