There is no need to sync on receiver side (bad wording on my side) but just be able to correlate data with media frames. Anyone, please correct me if my understanding is incorrect.
All of which would be entirely possible with the existing SCTP transport using similar if not identical mechanisms.

Which SCTP already has.

Which brings us back to the essential argument - browser and server developers would rather work on 
something from scratch with QUIC than work on the existing codebase of SCTP. 
I understand that argument, but as one of the few people here to have worked with SCTP,
I’m here to say it isn’t anything to fear….
