I support this. It looks very useful.

One hopefully minor point I noticed:
I assume an AMT gateway would meet the definition of a gateway, if a request arrives at a router with an AMT gateway as the next hop RPF interface, but I don’t think there’s a path to the upstream router or an appropriate multicast address on the RPF interface, since AMT doesn’t provide a path to send non-IGMP/MLD packets upstream over the tunnel.

It doesn’t look like section 4.5 covers this scenario, or do I have it wrong?  I assume that having nowhere to send the proxied query packet, no reply will be received and it would time out, but I’m not sure how an implementation could satisfy the MUST in the final paragraph of 4.5.

Kind regards,
Jake
