Additional Information

This type of error would otherwise fit under the catch-all http_protocol_error type. In practice our customers have found it useful to distinguish parse errors that occur in the status, particularly for HTTP/1 responses with unusual reason phrases.

I do not see "invalid" used elsewhere in RFC 9209, but that's the word RFC 9110 uses to describe out-of-range status codes. I'm very open to naming suggestions here.
