BBR in kernel works for TCP because it's used for TCP congestion control. QUIC is built on top of UDP and there is no congestion control used for UDP, you implement it in your application/protocol built on top of UDP. From what I remember QUIC implementation supports BBR and Cubic as congestion control mechanisms.

Correct. QUIC also implements TLP. Main advantage is deployability since this is a user-space solution.
