Aha so there is an implicit HW dependency between the port and the
LED, that we just cannot see in the device tree. Okay, it makes sense.

I think there will be a day when a switch without LED controller appears,
but the system has a few LEDs for the ports connected to an
arbitrary GPIO controller, and then we will need this. But we have
not seen that yet :)
