Hi, Russ,

Thanks a lot for your feedback! In-line....

I have to comments.

1) I do not see this document as a BCP.  Despite the inclusion of the boilerplate, there is not a single MUST in the document.  I have no objection to an Informational RFC.

FWIW, version -04 had the following text:

---- cut here ----
5.  Security and Privacy Requirements for Identifiers

   Protocol specifications that specify transient numeric identifiers
   MUST:
---- cut here ----

This was changed in response to feedback we got. But we could add some text in that line, whether "MUST" or "SHOULD"

I believe it would be a shame for us to be unable to do a BCP on the topic, given the bad track the IETF has had with respect to transient identifiers, and given that, for multiple reasons, this effort has taken about 5 years so far....


2) The document is really about transient identifiers.  It does not only apply to ones that are numeric.

That's probably the case. However, the ones we assessed are all numeric identifiers. And those are the ones that we have analyzed in the companion document draft-irtf-pearg-numeric-ids-generation

Just curious: what are the non-numeric transient identifiers you had in mind?

Thanks!

Regards,
