In some countries, you can be court-ordered to decrypt the contents of a device if it can be proven that encrypted contents exist. With LUKS, there is no denying it; with plain dm-crypt and its lack of an encryption header, the device could just as well have been overwritten with random data.

-a already means "all". Having to indicate usb0 manually is already a proof that you have an unmarked cryptocontainer. Moreover this line exactly illustrates my point: what is usb0 depends on other plugged device and even his fast they are and may vary from boot to boot. I'm not quite convinced you can deny this line plausibly

In other words, to keep it plausible, it would have to be a stock feature across the board.
