The document defines a new TLS extension, called Encrypted Client Hello (ECH),
for encrypting a ClientHello message under a server public key. I think that it
is clear and well-written.

This extension is supported in TLS 1.3 (RFC 8446), DTLS 1.3 (RFC 9147) and
newer versions. It is intended to work with various transport protocols (TCP,
UDP, QUIC), by improving their security and privacy.

>From an OPSDIR point of view, section 8 on Deployment Considerations is quite
relevant since ECH requires changes to client, client-facing server, and
backend server. In this regard, compatibility issues and deployment impacts are
reported. Some considerations about the implementation choices are also
mentioned in the text.
