I didn't dig into the 1wd spec too much so I'm not sure what @huitema's rationale was for incorporating the timestamp into a new frame. 

Reflecting on my immutable thinking model, this is probably influenced by have more familiarity with the HTTP/3 layer, which does not require a-priori negotiation of frames, and so meddling with the layouts of frames is problematic. QUIC extension works slightly different, but I'd still err on the side of not meddling with frames. Using types allow for failing early and explicitly e.g. "extension foo adds frames X and Z, it deprecates A and B. Reception of A or B is connection error"
