With the frequency most of the Arduinos run at, I thought I saw the max step frequency to be around 4000 per second. That works out nice with a 1.8 degree stepper (200 steps per rotation) with 1/16th microstep as 3200 leaves plenty of wiggle room for a rotation per second. Going up to 32 you can't do a full rotation in per second. You'd have to slow down the rotational speed to ~1/14 what you could with 1/16th stepping. So while your microstepping accuracy goes way up, your speed goes way down. And I'd honestly have serious questions as to the accuracy of 1/256 microsteps with the NEMA 17 motors we usually use.Quote

but it's more than 32 microsteps too

Yes, that video. I'm not sure how you can not fully agree. I just basically rephrased exactly what he says. At about the 2:15 mark he talks about the quiet mode and describing it as "gently suggesting that now maybe it should move to that spot and if it doesn't, the driver isn't going to take any extra efforts to get it there" and then follows it up demonstrating minimal torque by stopping and pushing the x-carriage the opposite direction intended, and then just flat out saying it makes it pretty useless for our use with 3D printers. He even shows in the datasheet where it says only for low and medium velocities. Seems pretty cut and dry.
