I think a choice within DMARCbis is a bad idea. Effectively the choice
exists. Evaluators will have the choice to stay with an RFC 7489 design or
to upgrade to DMARCbis.
The incentive to upgrade is not clear. DMARC filters can run based on an
obsolete version of the PSL with no inconvenience, for a different flavor
of "upgrade". Indeed, according to John's figures, we could have done
without any psd= tag.
Using obsolete data is a bug, not a feature.
Or using data that is accidentally correct most of the time, where
alternatives are available. Either way, +1.
+1 from me too. Note, though, that the (current) DNS is accidentally
correct most of the time, as far as our Tree Walk is concerned.
