Yes, the latter is conceptually a generalization of the former and it can
be tempting to use the general form. Beware that pids controller would
need to retain its existing API (and the behavior of being an
independent controller) and that would be IMO exceptions
counterweighting the generalization.

Technically it might be possible but I can't see the benefit (but maybe
you envisioned something else where my reasoning won't apply).
