Gen-Art Early review of draft-ietf-pim-3228bis-05

I am the assigned Gen-ART reviewer for this early review of this draft. 
The General Area Review Team (Gen-ART) reviews all IETF documents being processed
by the IESG for the IETF Chair.

Summary:  This is a simple update of the IANA allocation processes for a small number of fields in the IGMP and MLD protocols previously mostly covered by RFC 3228 and provides unification of processes for the IPv4 and IPv6 versions of the protocols dealing with multicast listener discovery.  The document is ready for last call except for a couple of minor nits.

Major Issues:
None

Minor Issues:
s6.1:  Given that this document will obsolete RFC 3228 and incorporates the whole function of RFC 3228, I do not think the RFC 3228 should be normative and should be relegated to Informative.

Nits and Editorial Comments:
Abstract and s1:
I suggest:
OLD:
This document obsoletes [RFC3228].
NEW:
This document obsoletes [RFC3228] and unifies guidelines for IPv4 and IPv6 protocols.
ENDS

s2.3: The comment from s2.2:
   The initial contents of this requested registry should contain the
   E-bit defined in [RFC9279].
should be duplicated in s2.3.
