A cop asking you to remove the key from the ignition, or just ripping it out of the ignition without your knowledge are two different things. I believe that the first principle is equal to a cop asking you to get out of the car so he can "detain" you, or cuff you for his safety. It doesn't mean you're under arrest, but it's still legal for him to do till the road stop is complete. Removing a key wouthout your knowledge should be deemed illegal. If you're going to be stopped you're going to shut the bike down, get off, and remove your gear anyway, so being asked to remove the key shouldn't be that much of an issue.
