S 2.1.
  The indicator names inserted by the client and server are different to
  ensure that these names will not produce a match, and will be neutral
  with respect to key exchange algorithm negotiation.

Can you explain what "neutral" means?


S 2.2.
If a client or server offers "ext-info-c" or "ext-info-s"
  respectively, it must be prepared to accept a SSH_MSG_EXT_INFO message
  from the peer.

Can a server send ext-info-s if it did not receive ext-info-c?


S 3.4.
  A client sends "y" to indicate its preference that the session should
  be elevated; "n" to not be elevated; and "d" for the server to use its
  default behavior. If a client does not send the "elevation" extension,
  the server SHOULD act as if "d" was sent.

You need a citation for "elevated."
