I would definitely not say that we re-invented pacing! One version of the question we looked at was: how low a pace rate can you pick for an ABR algorithm, without reducing video QoE? The part which takes work is this "without reducing video QoE" requirement. If you're interested, check out the paper!

that is certainly an interesting economical optimization problem to reason about, though imho somewhat beyond technical merit, as simply letting the client choose quality and sending the data full speed works well enough.

addition:

i totally agree that things have to look economical in order to work and that there are technical edge-cases that need to be handled for good ux, but i dont't quite see how client-side buffer occupancy in the seconds range is in the users interest.
