Like I said, I respect Mahesh’s input as original author.  It’s hard to 
disagree with that.  That said, I think the original RFC8519 is useful on its 
own, and these proposed extensions add value that may not be needed by 
everyone.  I’d much rather see this new work progress rather than opening up 
RFC8519 to more comments.

Subject: [netmod] ACL Extensions Draft
The question in the WG for the ACL Extensions draft was whether the draft 
should be an augmentation of the base ACL model, or a -bis of RFC 8519. Lou 
brought some clarity by saying that if the base model could exist by itself 
without these extensions, then it should be treated as an augmentation, but if 
there are fundamental additions to the base model that should have existed from 
day 1, it should be a -bis.

Looking at the changes being proposed by the draft, I see a combination of 
extensions, e.g. defined-sets, and changes that are fairly fundamental to the 
usage of ACL model. I am sorry that we missed them in RFC 8519. Examples of 
that include definitions for ipv4-fragment, ipv6-fragment, mpls etc. It is for 
those fundamental definitions, my personal opinion (and as author of RFC 8519) 
is that it should be -bis.

Cheers.
