HTTP/3 is everywhere but nowhere
Small websites gain from reducing roundtrips on connection too. Fast websites are nice

HTTP/2 already reduces roundtrips.

HTTP/3 even more so due to QUIC's shorter handshake process.

At the cost of head-of-line blocking - one dropped TCP packet delays all HTTP/2 streams.

Yes, but head-of-line blocking is a different thing than round trips.

A dropped packet requires a retransmit which is effectively a round trip. Introducing shared fate by bundling many requests into a single TCP connection results in more requests being delayed by round trips per dropped packet.

Isn't head of line blocking a problem with the design of web servers?
