Shepherd writeup

This document originally lived in draft-gont-predictable-protocol-ids along with draft-irtf-pearg-numeric-ids-history and draft-gont-numeric-ids-sec-considerations and was later on broken up into 3 separate drafts. This particular document concerns itself with analyzing the security and privacy aspects of numeric identifiers used by various IETF protocols and provides guidance on writing algorithms that generate transient numeric identifiers.

In general this document is well-written and comprehensive. It went through  review in its previous incarnation and the PEARG chairs asked for an early TSVART review that raised comments that the authors addressed in subsequent revisions. No additional comments were received in the PEARG Last Call. 

The chairs consider this document ready to proceed to IRSG last call.
