The TLS + QUIC layer makes UDP safer to use, but a lot of networks will likely still block for awhile. Scalemates.com flipped the switch to enable HTTP/3 and almost immediately HTTP/3 traffic rose to ~13% of all requests on the landing page, ~49% for all pages in total.

Browsers will cache tools popular among vocal, leading-edge developers. There's plenty of space for caching most popular frameworks. The best available proxy data also suggests that shared caches would have a minimal positive effect on performance. Browsers now understand the classic shared HTTP cache behaviour as a privacy bug.
