This issue is still open and I don't see a pull request attached to it.
Was it resolved some other way?


IMHO, the generic steps for a DNS Tree Walk *can be amended* by making it stop at step 2 also if the record has psd=y. In that case we must reword step 2 in Section 4.10.2 to say that the domain where the tree walk started is the Organizational Domain.

Note that stopping also for psd=y is the only difference between step 2 and step 6. So, if this modification is accepted, step 5 can just say "Goto 1."

The current steps were discussed in June 2022:

I don't recall we considered PSDs whose subdomains are PSDs where the parent forgot to publish psd=y. Daniel-t brought up that issue in github.


Best
