Hi Stephen,

ECH-09 is meant to use HPKE-07, as declared in the body:
https://www.ietf.org/archive/id/draft-ietf-tls-esni-09.html#name-encrypted-clienthello-confi

Although it looks the draft didn't get updated in the references somehow:

[I-D.irtf-cfrg-hpke] Barnes, R., Bhargavan, K., Lipp, B., and C. Wood, "Hybrid
Public Key Encryption", Work in Progress, Internet-Draft,
draft-irtf-cfrg-hpke-06, 23 October 2020, <
http://www.ietf.org/internet-drafts/draft-irtf-cfrg-hpke-06.txt
<https://www.ietf.org/internet-drafts/draft-irtf-cfrg-hpke-06.txt>>.

Also, +1 for targeting ECH-09 for interop!

Chris P.
