This really should get merged ASAP.

My toolhead crashed into the bed when I set up Klipper for the first time :(

I probably should have used my finger to check the trigger before trying to probe the bed, so that's on me... but quite frustrating having to debug and finally figure out it was related to official documentation/configuration.

From the Klipper docs ¹:

Most BL-Touch devices require a pullup on the sensor pin

Same here.... It should really just work, I mean they have had multiple years to fix this, I'm starting to regret my purchase..

Hi, this is also true for BLTouch. The default config works in Open Drain mode, which requires the Pullup resistor to avoid a floating signal.
This is true for at least BLTouch 3.0, older BLTouch would be from before 2017
