Yes, please.

While adding custom files to sysfs may appear easier, we'll need
"led-specific-triggers" for other reasons.

And for the record... Handling 3 LEDs as one is not something usual in
the LED subsystem; I guess it makes sense in your specific case, but
hopefully noone will copy that design.

(I guess they are not individually controllable?)
