Admittedly, I see some value in having the mute button mute things regardless of what userspace is doing, but I don't see *much* value in it. And, arguably, if that behavior is actually desirable, it should be available on all laptops, not just ThinkPads.
Things start to get tricky when you think one step ahead and ask yourself what outputs the button and the LED really should control. We touched the topic briefly when discussing LEDs on the audio meeting last year. I'm attaching my presentation for reference.
(The outcome of the discussion about the mic mute LED was "we don't know, go ask designers", and well, you probably know the result, as we ended up with "The internal card's mics" for the mic mute LED.)
