Jingrong,

The agenda stands as a reflection of the decisions of the WG according to
our procedures and charter. From the charter:

https://datatracker.ietf.org/wg/bier/about/

7) BIER in IPv6 : A mechanism to use BIER natively in IPv6 may be
standardized if coordinated with the 6MAN WG and with understood
applicability.

As of now, the WG has decided that modifying the v6 header to encode BIER
is no longer native v6

Please review the minutes from IETF 104 in Prague:

https://datatracker.ietf.org/doc/minutes-104-bier/

There was a productive discussion in the room. The consensus in the room,
which was confirmed from the list, was that this work will focus on the
problem statement first. If one or more unique use-cases are presented that
require a new encoding or encapsulation then we can address solutions to
these use-case in the associated drafts. If these solutions are out of
scope of our charter, we can propose changing the charter to include this
work at that time, as necessary.

I'm sorry the WG is not moving as fast as you like. I agree with you. :) We
have more than a handful of active drafts ready for WGLC and we can't get
volunteers for Doc Shepherds. Some WGLC email responses were so
depressingly low it can't be considered much of a consensus. But it's what
we have and where we are at this time.

I look forward getting deeper into the use-cases draft this week. Thanks
for you help and patience.

- Shep
