I agree on DMARCbis. I don't think advancing this draft has a significant effect on that. Worst case, if DMARCbis is done before we can reach any conclusions about PSD DMARC, then we publish DMARCbis without PSD DMARC in it. I don't see anything about PSD DMARC being inherently on the critical path for DMARCbis. I suspect the current major obstacle to DMARCbis is that the question of how to take the PSL out of the equation is unsolved, despite one IETF WG that was supposed to be dedicated to the question. I don't think not publishing PSD DMARC helps move DMARCbis forward, so I think it's a false choice.
