I fully agree. Thank you Ben!

Hi Yaron,
Thanks for the (multiple!) reviews.
My understanding is that the intention is not to allow "server_name" in all
CertificateRequests but only specifically in the ClientCertificateRequest
case. I think it can be helpful to notate that with a "CR" in the "TLS
1.3" column of the registry but we would need some further clarification as
to what that notation actually means. I left some suggestions for how to
do that in my ballot position, but to summarize: a "comment" column in the
registry would be great for this, and failing that a note in the IANA
Considerations of this document to clarify what is and is not being
registered would probably work as well.
Thanks again for highlighting this point,
Ben
