  "message": "Introduce Object ACKs (OACKs) to MoQT.\n\nOACKs let the application receiver acknowledge that it has received (and potentially processed) the object.  In addition to that, we also communicate how far off from the deadline the object was received.\n\nThe sender want to know this information if it is in a position to adjust the send rate:\n- when it\u0027s a 1:1 connection and it controls the video bitrate,\n- when it\u0027s doing sender-side ABR.\n\nThe reason we want to do MoQ-level ACKs is that the alternatives are not as good:\n- using QUIC ACKs directly breaks layering and is infeasible with web APIs\n- using a building up queue as a signal is possible, but the queue takes a time to build up, thus making it a delayed signal\n\nPiperOrigin-RevId: 668549384\n",
