Seconded. Sure, a userland daemon would add flexibility but it would
also add considerable overhead and would be useless during kernel
startup when LEDs/LCDs might be a valuable debugging aid.
Same about kernel panics.

Definitely, it may not always be possible to come up with a reasonable
and complete default wiring and this default may or may not be what the

Yes, it would be nice if we could use any gpio as output.

I've been volunteered for it as well ;)
