The current DMARC spec essentially says the first part, that you have to find
the org domain but waves its hands about how.

I really would not want to make the PSL a requirement for any spec.
The people who maintain it say in large letters on their web site 
not to use it for any new applications.

There's no technical bar to doing something else.  I have running code
for a DNS lookup technique that does everything the PSL does without a
tree walk at https://github.com/jrlevine/bound

The problem is that we seem unable to agree on any PSL or not-PSL like thing.

R's,
