I agree with mike and oppose the adoption of this draft.

For example, this document proposes 2 options for the fragmentation in BIERin6 in section 2.
One is using an IPv6 header before BIER header, but this will enforce every BFR to assembly and re-fragment a packet.
The other is to use a Fragment header after BIER header to avoid intermediate BFR to do the assembly and re-fragment,
however I don't think it is a mature and accepted solution to support this draft to be adopted.

Thank you.

Oppose.

We are unfortunately no where near consensus on this topic including this draft. We'll likely see that during this adoption call.

Adrian's suggestion for consensus remains the best I've heard: simultaneously call to adopt both solutions as experimental.
