Well. I mean, as long as we don't mention XEP-0136, right?

Broadly, yes, though much of the requirements section is actually concerned
with features of XEP-0136 that are not considered requirements.

A possibly minor issue is that the archive identifiers present are assumed
to have an unbounded lifetime. In at least some servers stanza ids are
computed from internal database identifiers, or constrained to being UUIDs,
and so on - and these rules will not be the same between servers. Therefore
if you're switching implementation, copying the data from one to another,
the archive identifiers will necessarily change. No guidance is given in
these cases, but it might be useful to have a validity indicator. Or that
might be catering to a very niche case.

Either way, this is very much a non-blocking comment, but I thought perhaps
worth raising.

None beyond the Security Considerations section.

Seems so, aside from the typo in the last paragraph of §6.1.1.
