"Malformed" is defined by [Section 4.1.3](https://quicwg.org/base-drafts/draft-ietf-quic-http.html#name-malformed-requests-and-resp).  If a specific header is not used properly, that's an error at the semantic layer; the server might send you a 400, but that's a successful request/response as far as HTTP/3 is concerned.

#3334 adds the advice without any change to what is a stream/connection error, meaning that malformed messages are stream errors and the rest remain connection errors.
