I think "overwrite modus-operandi-theme and modus-vivendi-theme with
a small package which depends on modus-themes for compatibility and prints some
kind of deprecation warning, maybe via the autoload mechanism" is the
better way forward (but this can be done calmly once the `modus-themes`
is confirmed to be in good shape).
