> By nature of being above UDP, QUIC is layer 5 or higher.
That doesn't seem like a fair characterization. In some TLS-based VPNs, IP is sent over TLS – does that make it a layer 7 protocol?

SCTP is also usually encapsulated in UDP when used in WebRTC data channels, yet I've never heard it being described as anything other than a transport layer protocol.
