It'll be a post by a non-subscriber I guess, in which case it will
appear later.

Yeah, it's just asking for trouble and seems to defeat the point of
having the LED in the first place - aside from the general issues with
it being software controlled it'll require specific userspace support to
set it.  Users won't be able to trust that the LED state accurately
reflects if they're muted or not.  Your proposal is more what I'd expect
here, I'm not sure we can do much better with something software
controllable.
