Maybe we're having an English language question.

If something isn't enabled, doesn't that imply that it's disabled?  Last
I checked, enabled/disabled were binary operations.

If I enable the clutch in my car, my car moves (assuming it's in gear).
If I disable it, the power is no longer going to the drive wheels.

It's either enabled or disabled.  There is no 'in-between' state.
(Well, unless you're riding the clutch, but that's not considered a
valid state, since the behavior is undefined, as well as bad for your
clutch. :)
