Also please be aware that using a regulator in the pwm backlight will
instantly break all existing users. That's hardly your fault though.

Sorry, I don't see why. Could you elaborate on this?

All existing machines will start failing during probe as they won't be
able to find the regulator - you should ideally make sure everyone in
mainline gets an appropriate regulator set up.
