As this suggestion makes total technical sense to me, I would say to 
change that line in something like:

"If a support for device ports operating also in L2 mode is required, 
then the device must support MLDv2 snooping [RFC4541]"

Now, the chairs and community needs to decide, if that falls under 
errata or is that a bigger change.

Personal opinion: adding RFC6946, RFC 6620 (SAVI FCFS), RFC 6583 (NDP 
cache exhaustion) and other RFCs to the document - that's a big change 
and should go in next editorial of a -bis. Changing MLDv2 snooping from 
unconditional to "if functionality required" and still in mandatory 
section - that might be seen as not that big change after all.

Cheers, Jan

P.S: Compiling the lists of changes, will post the link when 
considerably long enough ;)
