I doubt applications would provide more reliable information to the QUIC library than they would to the kernel.
The main difference as I understand it is that QUIC allows multiple separate TCP-like streams to exist on the same negotiated and encrypted connection. It's not fundamentally different from simply establishing multiple TLS over TCP connections with separate windows, it just allows you to establish the equivalent of multiple TLS + TCP connections with a single handshake.
