As a young network engineer (no historic perspective) and only SMB and enterprise experience. It seems like the intention was to allow these to be publicly routed, but it would be a nightmare to implement so it never was.
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. -- Niels. -- "It's amazing what people will do to get their name on the internet, which is odd, because all you really need is a Blogspot account." -- roy edroso, alicublog.blogspot.com
