I don't think that works.  MLDv2 is required in order to support SSM
as per [SSMARCH] and draft-holbrook-idmr-igmpv3-ssm-05.txt.  So, it
needs to be worded as it was originally written.

The issue with MLDv1 and MLDv2 interaction described very well in the
MLDv2 spec.  There is nothing that needs to be in node reqs to deal
with that case imho.
