I have reviewed this document and I think it is ready to go with
one exception, namely the Recommended column.

The RFC 8447 standard for "Recommended=Y" is:

   Per this document, a "Recommended" column has been added to many of
   the TLS registries to indicate parameters that are generally
   recommended for implementations to support.

I think there's a general expectation that we want people to
implement and deploy these algorithms, and I would expect
that the X25519 and P-256 versions to be widely deployed,
at least on the Web. Therefore, I think we should mark all of
these as Recommended=Y. I note that this would require
advancing this document as Proposed Standard. We should do
that as well.
