Can the LED framework be used without having the LED exposed to
userspace ?
I believe the correct question here is "can the states of some leds be
read-only from user perspective" (this way any changes into led subsystems
looks less intrusive, esp. taking into account that subsystem is de facto
unmaintained).
I think the answer to that is yes:
