I agree with others that SHOULD implement both, or other variations on
SHOULD, are not helpful. They will anyway be ignored and amount to more or
less the no-interop situation we're in if we continue on the current path
and have no consensus.  No consensus means the various players doing as
they prefer, which is what they'd do if there is a SHOULD.
