I guess what OP meant is, the court can compel you to do so - and yes, already. Basically the court can compel you to provide any information it needs in the course of legal proceedings, and until you do, fine and/or imprison you indefinitely. But, you know, there must be legal proceedings, the court must be satisfied that the information is necessary, etc. The guy at the border can't do that, on their own initiative. But of course, they can just not let you in.
