Quoting myself:

> Another wrinke is: What should an endpoint do if it receives an error that references an unknown frame type? An endpoint MUST ignore unknown types, and we have these in the form of grease frame types with values that are included in the error code space.

Endpoint X receives a GREASE frame and for whatever reason decides to issue a stream error with a HTTP_MALFORMED_FRAME code that covers GREASE. Endpoint Y receives the error code, and takes this as a signal that X didn't follow the rule to ignore the frame. So it sends a connection error back?

This is an edge case yes, but I think it is another argument against declaring a very large codepoint space that is mostly useless in practice.
