What the clause requires
Treat 103 as informational and keep reading for the final response. RFC 9110 §15.2 makes this a MUST: a client "MUST be able to parse one or more 1xx responses received prior to a final response, even if the client does not expect one". Ignoring the hints is fine — a user agent MAY do that — but closing the connection is not.
Judged against RFC 9110, RFC 8297.
