While I agree that lack of a CA certificate with the matching naming
really doesn┬╣t matter, breaking name chaining seems like an odd way to
maintain ┬│ritual compliance".  Why not bump the version number instead?
v4 could be defined as a pre-certificate containing a poison extension and
a serial number that matches its v3 counterpart.
