The internet's plumbing got a new protocol. Most people never noticed
QUIC moved a large share of web traffic off the transport layer that served it for forty years. That is the point.
The standards body finalised the protocol in 2021, after years of running it at scale inside the largest web companies. It carries connections over UDP, with encryption built in and no head-of-line blocking. (J. Iyengar and M. Thomson)
For a reader on a patchy mobile connection the gain is pages that keep loading when a packet is lost rather than stalling.
Why it took so long
Changing the transport layer means changing every middlebox between a phone and a server. Running over UDP was a way around them, and it worked.
