Multicast was never popular with operators because it had the
potential to create a lot of state across every router in a network,
as well as lead to uncontrolled explosions of traffic, especially in
network designs that relied on virtual circuits for significant
portions of last-mile infrastructure.
Some of these problems were addressed with SSM, IP DSLAMs, and having
consumer connection speeds be significantly faster than what a Full HD
video stream requires, but given that major network providers already
don't have the in-house clue to implement IPv6, multicast will be very
low priority.
