We don't really have any real principles that we agree on for deciding what error codes we are describing.

Proposal:

1. if the error carries distinct semantics (like stream rejection in HTTP), then it gets a new error code

2. if the error is frequent or particularly significant, then it gets a new error code

3. otherwise, target a more generic error code that identifies the broad area of the protocol

4. finally, if there is no more specific applicable error code, use PROTOCOL_VIOLATION
