@dtikhonov "My point is mostly that one technology already works." - I'll specifically disagree with this point.  HTTP/2 has been an RFC for 4 years now and according to Patrick Meenan's surveys, a huge fraction of servers don't support HTTP/2 priorities and clients have somewhat odd usage patterns, with Chrome specifically trying to re-create strict priorities and Edge ignoring them entirely.

The complexity has also kept HTTP/2 priorities out of the web APIs, because it's clear the full functionality is far too complex for web developers and it's hard to agree upon what should be surfaced.

The target should be something the majority of implementations will implement, even if it's not their ideal solution.
