Lucas said: "With that in mind, how would you foresee the running code aspect of the process. Would there be some opportunity to do interop such as at the Hackathon?" [BA] One can argue that the draft milestones are optimistic, given experience. So we can increase the timeline to better conform to reality. >From the comments, it seems like the simplest work items (e.g. WebTransport for QUIC) are likely to be implemented first; the HTTP-related items will be likely to take longer. Having successful interop tests/Hackathon experience will confirm that the specifications are sufficiently clear to yield interoperable implementations. Victor said: "I also feel we should be somewhat more explicit about what points we expect to coordinate with W3C (i.e. we should coordinate on requirements, but not on protocol details)." [BA] That is a good point. The current Draft Charter does not include a requirements document. Would it make sense to add that as a work item?
