(Whiteboard: [necko-triaged])

To my understanding, HTTP/3 allows seamless connection migration via QUIC, but HTTP/2, relying on TCP, doesn't support this due to the need to reset connections when the network changes.

While seamless migration isn't possible in HTTP/2, we could potentially improve how a change of network is handled during connection establishment.

Switching networks mid-connection can happen frequently for mobile users.

Bug 1706377 made progress in this space, but I understand that the changes are mostly for VPN users.
