Note

The role of the designated expert is described in [RFC8447].
The designated expert [RFC8126] ensures that the specification is
publicly available.  It is sufficient to have an Internet-Draft
(that is posted and never published as an RFC) or a document from
another standards body, industry consortium, university site, etc.
The expert may provide more in-depth reviews, but their approval
should not be taken as an endorsement of the extension.
