Excluding the length has diminished benefit if it takes 8 bytes to encode the frame type (I am referring to #2253, with which this proposal is linked).

I am not against future-proofing the format, but both this and the varint type proposal seem very theoretical: _there might be someone who may want..._ etc.  For example, there have only been [two extensions](https://www.iana.org/assignments/http2-parameters/http2-parameters.xhtml#frame-type) to the HTTP/2 frames.  Has extending or experimenting with HTTP/2 frames ever been a real problem?
