The document is nicely written and easy to understand even by someone who is
not familiar with BIER.

I have one minor question/comment though.
If I understand correctly (from looking at rfc8279), when the BIER header is
removed,  by default the TTL/Hoplimit in the payload is not updated. Does it
mean that if the BIER header is removed one hop earlier (with PHP), the last
hop might become visible to traceroute-like tools? Not sure if it should be
mentioned in the operational consideration section?

Thanks!
