Sorry to say but this is a terrible idea. Knowing someone is under or out of protection is a very valueable data to obtain that easily and publicly. This will kill quite few tricks and strategies that can give a player edge. It is fun to have your or enemy province come up with a plan for series of attacks just before tick, but by miscalculating or a suprise factor a critical attack is denied by protection and all plan fails. Managing that needs quick thinking or having plan B under your sleeve. Or sometimes you may choose to break protection before normal time to suprise the plans on your kingdom. There are more that can be done with this info being hidden to public.
