Well, of course: I meant "a secure repository /for the user/" :) I.e.: you could trust the law (as well done and respected), or you could stay on the safe side. Taking a look around, I'd take the safer side.

Like opening a trunk through feed waggling or radio control of windows for those who are prone to leaving open sunroofs during storms - at the cost of adding complexities and possibly exposure to faults and malice... The first violently blinking one being "no need to press a button to open the car anymore, proximity suffices".

Everyone makes their own decisions on tradeoffs: the option - which they may like, which may leave them indifferent, which they may not want at all - should not be shoved in the throat of the users.
