They still pre-emptively ban numbers, for instance if they represent something illegal: "Any image file or an executable program can be regarded as simply a very large binary number. In certain jurisdictions, there are images that are illegal to possess, due to obscenity or secrecy/classified status, so the corresponding numbers could be illegal." Also, the concept of "numbers yet to be found" is philosophically questionable.
