Why would it need to? It could look at default triggers for the led if it really wanted to. > I'm sure you'd also not like to see 2**7 triggers implemented in rfkill > to cover all the possibilities. Are all the possibilities useful? I assumed about 2 are.

What semantics does "airplane mode" have?

I'm saying that LED maintainers should be Cced, to keep the interfaces consistent.
