#2While I'm sure brake dust is harmful, this study was done on cells in a lab (not even mice).

#3> researchers grew human lung cells in a lab and exposed them to dust from car brakes and from diesel tailpipes, finding that brake dust caused greater injury to the cells.
I couldn’t tell if the study found that car brakes are more harmful than exhausts, or that car brake chemicals are more harmful than exhaust fumes - but that may not be significant because they are produced in less quantities.

#4I wonder if this will spur mandatory regenerative braking in all cars, eventually, as a means of reducing pollutants?

#5I wonder if this means another advantage for EVs in terms of environmental friendliness.

Or even just HEV and PHEVs with slightly larger battery packs.

#7I think this is missing out on the big issue - tyre pollution which contains really nasty chemicals that inevitably get washed into rivers and waterways.
Also, car-shaped EVs often use regenerative braking which will reduce the amount of brake dust pollution, but with their increased weight and powerful torque, they produce a lot more tyre pollution than ICE vehicles.

That's the fly in the ointment, they're not. The increased mass and torque actually produces more tire dust than a ICE car.

You don't even need a huge battery pack for dynamic braking. It's the architecture of hybrid cars that allows them to regeneratively brake, even if the battery is full, by using the engine as a pump. Although this doesn't arise in practice, hybrids could dynamically brake down a grade of any length, which BEVs can't guarantee.
