perhaps being greyed out is a failure of 1.4.1 and it becomes a non issue if accessibility testers/tools review disabled elements for contrast. I think we have to set a minimum contrast level for them to test against. That being said...I agree - there needs to be a different way (other than a dimmer grey) to indicate visually that something is disabled.
