This is from an industry perspective and not specific to Juniper. BIER won't really happen without hardware support which is coming but will not be compatible with a lot of already deployed hardware.
There was some IETF work going on to figure out how to map multicast to SR-MPLS but it kind of died off last year. TreeSID is more of a Cisco solution, and relies on an external PCE to build the multicast tree at every branch point across an SR-enabled network. Near-term mLDP specifically for multicast, without unicast enabled, is a solution. Ingress replication is becoming a bit more popular as multicast as an overall percentage of traffic has continued to drop.

As we are possibly removing mLDP and RSVP from the network in favour of SR(-TE) what are people doing to fill this void. There were some drafts being worked on last year and if I recall one that seemed more "developed" was "Bit Index Explicit Replication", but I haven't heard anything more about this topic and it hasn't been mentioned in the thread so far. Any comments?
