That would break credit card readers, barcode scanners, and special purpose keyboards (like video workstations).
I suppose you could rely on a binary code, where the user is instructed to press any two keys to repeat the code, or if there is only one key (or it's a barcode scanner), to enter the same input multiple times, separated by long and short pauses.
Still seems like it would be difficult for the average user.
