I just lost a morr elegant reply so this might sound curt.

The proposal seems to make tree entry operations more deterministic. However, tree management like pruning and shuffling based on stream closure seems non-determinisitc. H2 has problems in this regard already.

Some H3 implementation experience is already bringing to light designs that have two world views of stream state: one for QUIC transport and one for H3.
