Variable-length integer encoding for HTTP/2 frames

Hi,

I was thinking about some new extension frames, which would be defined in HTTP/2 and HTTP/QUIC. I saw a theoretical opportunity to reuse QUIC’s Variable-length integer encoding [1] for handling the optionality of some Frame field-types. QUIC (and HTTP/QUIC) frames already make heavy use of encoding, so I wondered how the concept of backporting the feature to HTTP/2 frame *payload* might fly. (Section 4.1 of RFC 7540 says that the structure and content of the frame payload is dependent entirely on the frame type).

Any thoughts that can be shared on implementation complexity?

Any opinions on if this is something that is desireable/undesirable for HTTP/2?

Kind regards
Lucas
