QUIC supports active connection migration.
Neqo, the Firefox QUIC implementation, [supports])(https://github.com/mozilla/neqo/blob/main/neqo-transport/src/connection/tests/migration.rs) active connection migration. This is also tested by the QUIC interop runner.
With https://phabricator.services.mozilla.com/D232499 we always create a new QUIC connection on network change.
We might want to consider leveraging QUIC connection migration feature on network change instead.
(Note that not all QUIC servers support QUIC connection migration.)
See also Bug 1910991.
A good first step might be to collect metrics on how many servers support QUIC connection migration in the first place, i.e. how many servers do not send the disable_active_migration QUIC transport parameter.

Telemetry on how frequently this (i.e., connection change) happens would be good, too. If we don't have that already.
