Most usages of a 'bool' are taking up at least a byte, so everyone has 250-odd extra values to play with "at the hardware level" already if they really want.
This - we don't directly bit-address much in computing, so the idea that richness isn't there because of binary is kind of silly. The flexibility is there and you often pay for it either way.
On many 64-bit architectures, you actually waste 63 bits of extra padding for that boolean, for alignment reasons, unless you put some other useful data nearby in your struct (according to the alignment rules).
Luckily, this kind of waste doesn't happen often, but sadly, it does sometimes happen.
