Seems like it would be obviously bad to use anything other than the
system certs?

Are we sure that there are no other users of dirmngr that this change
will break?

+1, although does it need to run continuously to keep CRLs up to date?
Does socket activation allow for that?

Are those config files no longer used in the newer version?
