Hi, I'm writing to provide some information and am neither speaking for or against the proposal.

I should probably point out that there are other sources of IPv4 multicast address space if this is a consideration. Firstly, there are the Unicast-Prefix-Based IPv4 Multicast Addresses, which are assigned algorithmically. Every IPv4 /24 prefix gives the user a /32 multicast address from 234/8. If a network operator does not have GLOP or Unicast-Prefix-Based IPv4 Multicast Addresses, or has used all those addresses, then it also possible to request an assignment (https://www.iana.org/form/multicast-ipv4). There is no charge for multicast address assignments and there's no immediate danger of running out of multicast space to assign.
