I'm not sure I agree with the "correctness proof" argument.  EndOfEarlyData exists to protect against truncation attacks on 0-RTT data; as such, it's a part of record layer, not handshake layer.  In fact, it did not go into transcript before draft19, so most papers cited for handshake analysis in the RFC do not mention it (out of those that do, the INRIA/MSR analysis treats it as a record layer entity, and _TLS 1.3 in Tamarin_ explicitly states it does not model it at all).

Given that this is unnecessary and adds bunch of complex and ugly logic, I think we should remove this.
