> Yeah. I think we share the view that the approach proposed will have the same pros and cons that the prioritization scheme of H2 has. I think that's a good thing, because it helps people use the same approach when using the prioritization scheme.

I have a nagging feeling, the QUIC streams can close in non-deterministic order from the remote peer perspective. This risks a H3 priority scheme that looks similar to H2 on paper but behaves quite differently. In the worst case this requires holding more state on the server in order to increase the chances that the client and server have similar global views.
