Except that bitrate is highly variable; a high quality stream of static content can use way less bandwidth than a lower quality stream encoding a lot of motion.

Now keep in mind they’re continually developing; perhaps testing different scaling preferences, or different codecs like AV1; suddenly you need a host of different bandwidth:estimated quality rates, that change over time and need to be kept in sync with client side changes… it’s not worth it
