Flatbuffer binary encoding of existing json spec?

Would a flatbuffer binary encoding of the existing json protocol spec for the matrix events be considered?

I experimented with encoding the existing json schema as binary using flatbuffers, and it did appear to work alright for `m.room.member_example.json`. I presume it would be fine for other messages, and that the flatbuffers schemas could be automatically generated with a tool from the matrix-spec repo (Meaning potentially no need to maintain a separate binary protocol specification).

I published my test here - https://github.com/matrix-hacks/matrix-flatbuffers

... I believe this would allow clients and servers to completely ditch the need for json parsing/encoding which relieves clients of a lot of their code size and complexity, while increasing message handling performance significantly -- all relevant for minimal/embedded clients written in C and other low level languages.

Flatbuffers already has language bindings for Go (and python and C++ and javascript and many others).

Start by reviewing the existing JSON protocol specification in matrix-spec and the proof of concept in matrix-hacks/matrix-flatbuffers. Determine whether schemas can be generated for the other Matrix events and whether the proposed encoding preserves protocol compatibility. Done would require an agreed design and implementation scope for binary client and server support.
