It is 100% possible to fix excessive downstream buffering from some
misconfigured device with a shaper on the download  *on the CPE or
home router*.

I have been doing that for 15 years. So has everyone that uses nearly
any of the shapers that are available for Linux, at least.

doing it yourself, right, requires a good measurement, and you lose
just a little bit of single-flow bandwidth - typically 5% - but you
get it all back with faster tcp ramp up times, huge improvements in
dns lookups, voip, gaming, and other traffic.

it generally works way better than policers do.
