Hello, Gyan,

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

Note: we're not targeting, specifically, pervasive monitoring.

We're essentially targeting security and privacy implications of 
transient numeric IDs in general. -- their implications are currently 
not covered by RFC3552.

Of course, some transient numeric IDs could certainly be exploited at 
mass scale.

Do you have in mind something like what's in Section 8 (and subsections) 
of; 
https://www.ietf.org/archive/id/draft-irtf-pearg-numeric-ids-generation-05.txt 
?

If so, and provided others agree, we can move (or copy) that section 
into this document.

Thanks, and Happy New Year!
