That definitely needs a forward reference to the IANA Considerations.
I don't think it's an RFC 2119 MAY, so it should read something like

  Extensions and profiles of this specification may expand this list
  with metadata names registered in accordance with the IANA Considerations
  in Section 4 of this document.

>   The authorization server MUST ignore any client metadata values sent

Silently, or with an error report?

This may be a nit but it confused me; surely it isn't metadata *values*
that are registered; it's metadata names and descriptions?

Nit:
----

I expected a reference, presumably [RFC6749], at the first mention
of OAuth 2.0 (in the first sentence).
