In article <20190228105902.4z3o6x7lavkhd4xk@mx4.yitter.info> you write:
>   RDBD is intended to demonstrate a relationship between registered
>   domains, not individual hostnames. ...

I think the intention here is what's known in DMARC-ese as an
organizational domain, which in practice means a domain whose
immediate parent is in the PSL.

I agree with your point about RRs, and as I've said a few times,
depending on what you think is hard or what is easy, the signatures
seem to add implemenation complexity without adding much actual
utility.

R's,
John

PS:

>(and I'm super annoyed the DBOUND WG failed), so I'll try to keep up.

Me too and I never really understood why.  Near as I can tell, my
proposal and Casey's were quite similar, but Casey's had a whole bunch
of added stuff that was hard to understand (I didn't) so people gave
up.
