> Never had to work with moq

Probably never had to work with (live) video at all? I think using moq is the dream for anyone who does. The alternatives—DASH, HLS, MSE, WebRTC, SRT, etc.— are all ridiculously fussy and limiting in one way or another, where QUIC/WebTransport and WebCodecs just give you the primitives you want to use as you choose, and moq appears focused on using them in a reasonable, CDN-friendly way.
