I don’t think threading the brake caliper should ever have been an answer, but I almost understand it for that clean-clean look on road bikes.
For MTB, PM basically cannibalized IS mount so with increasingly rare exceptions there aren’t than many relevant mounts anymore. Especially when 8” rotors get standardized at 200mm instead of 203mm (this year?).
It comes down to not fixing what ain’t broken. Introducing another mounting standard didn’t kill off the old ones. Now there’s just more options to support (for adapters AND brake calipers).
