draft-xie-bier-ipv6-encapsulation authors,

To date, there has been insufficient support on the list to adopt the
draft. It is the BIER WG position at this time that a review by the 6man WG
should take place before any further discussion in the BIER WG.

6MAN WG review aside, the draft still raises significant technical concerns
within the BIER WG. Adding replication information into a programmatic header
does NOT add replication to programmatic forwarding path, nor programmatics
to your replication forward path. It is at this point where replication
begins that all prograrmmatics cease due to the multi-point nature of
replication.  We have a nearly three decades of experience trying to use
unicast semantics to describe multi-point forwarding, and sometimes
learning from the past requires leaving it.

Thanks you,
Chairs
