Well, of course you can always implement bool as an int; C has done
this for decades, and it hasn't killed it. You can also implement
integers as strings - REXX manages quite well, and gets some
advantages therefrom. But having an explicit bool type has its
benefits too. Essential? No. Useful? Certainly.
