I’m concerned that some (admittedly rare) public suffixes with multiple
components are not well served by this algorithm, such as pvt.k12.ma.us.
Is there something peculiar with this domain? Please expand.
What happens if a domain that is not a public suffix publishes psd=y, either
accidentally or maliciously?
The interesting point of the Tree Walk is that it allows any domain to self
appoint itself as PSO or org domain, without going through PSL bureaucracy.
By publishing psd=y, a domain cannot use relaxed alignment, and may prevent
some receivers from issuing failure reports. By not publishing psd=y, a PSO
does a disservice to its independent subdomains, forcing them to publish psd=n.
A.6 Organizational Domain Discovery Issues
It seems much safer to just point to RFC 7489 for a description of the PSL
method than to repeat it here, where a non-careful reader might think that this
is a recommended method.
A.7 Removal of the “pct” tag
Already mentioned in 7.5.2, I don’t think this much description is needed for
something that isn’t part of the spec.
+1, the copied text is redundant.
