But shouldn't the "delayed media" attack still be transport agnostic? I mean, this can happen on QUIC and WebRTC SFUs. Anyway, I agree that while SFrame is transport agnostic, the chapter should not ignore the interactions with webrtc/quic and we must ensure that we provide a complete working solution regardless of the transport. If we identify that any further working items are required for a particular transport, we should at liaise with the appropriate working group for providing a solution.
