Re: Call for Consensus: Moving HTTP/3, QPACK and Recovery to the Late-Stage Process

[Gorry Fairhurst <[e-mail]>]

I don't think Recovery has that level of maturity yet.

To me, QUIC transport contains protocol specs that are the same as other 
protocols - albeit inter-twined with the encryption model and 
HTTP-specific aspects, but the recovery spec is focused on the protocol 
mechanisms, and needs to be correct with respect to the implications on 
other transport flows sharing capacity with QUIC.

In that space, we indeed need to get the spec correct. That may mean 
late comments (alas); but hopefully things will move faster if we focus 
on resolving issues and if work separates a little to http3 v recovery 
topic, actually most of the comments seem to come from a few people. If 
the process somehow impeded that I would be concerned.

Maybe I might feel happier after a detailed review of the latest text in 
24 and a check through the issues -  I undertake to do this before the 
Singapore meeting!

They/we might propose text back to HTTP/3, or they might define HTTP/3 extensions in an HTTPbis document, or they might do something else entirely.  This working group should consider the design team output if it comes before the document is done, and if not will need to make a decision about whether to proceed without it.

However, new issues against them will be judged for whether they contain new information (in particular, security or interoperability impact), a clear technical defect, or have significant (in the judgement of the chairs) support for further discussion. If the issue isn't well-described or atomic, it may be closed with a request to refactor, or refactored for you.
