You're not wrong. The key is convincing switch vendors to support

What you just wrote is the orthodox view in the IP multicast community.
When I read that, I hear the IP multicast community saying:
"We developed this IP multicast thing before 802.11 switches existed.
MAC-based receiver registration isn't needed on single-collision-domain
10Base5 Ethernet segments, so we didn't bother with that when we
developed the IP multicast protocols like IGMP.
"If the world is going to use 802.11 MAC-based switches, well then the
802.11 MAC-based switches had better emulate a single-collision-domain
segment, interpreting IPv4/IGMP and IPv6/MLD datagrams as necessary.
We're not going to change our way of doing things because we were here
first."
