> We find that over fast Internet, the UDP+QUIC+HTTP/3 stack suffers a data rate reduction of up to 45.2% compared to the TCP+TLS+HTTP/2 counterpart.

Haven't read the whole paper yet, but below 600 Mbit/s is implied as being "Slow Internet" in the intro.

In other words:

Enable http/3 + quic between client browser <> edge and restrict edge <> origin connections to http/2 or http/1

Cloudflare (as an example) only supports QUIC between client <> edge and doesn’t support it for connections to origin. Makes sense if the edge <> origin connection is reusable, stable, and “fast”.

Cloudflare tunnels work over quic so this is not entirely correct
