 OK, so there's a slight revision of (6.1), possibly Ran's other editorial
comments, and we have to resolve this registry issue.

IMO interoperability problems are an issue for whomever writes the
extension, not for you. For a flag that changes the format, this would have
to be negotiated. For something that doesn't, it might just provide
additional information or trigger some other behavior that doesn't break
the whole decrypt operation. I am not going to lie down in the road on this
registry issue (though Zahed might?) but it's a pretty small bit of text
and one decision on what RFC 8126 policy to use.
