How did you choose uint8_t vs. bool for this?

Ditto.

This didn't seen like a `bool` concept, but maybe I should be thinking in terms of storage size, not whether it's a Boolean concept. I can change it if you prefer.

Ditto.

If you use a boolean for storage, you don't need EnumTraits, because IPC knows there are only two valid values.

I'm curious whether IPC checks for 0x0 and 0x1, or just 0x0 and any value with any bit set. The latter seems less desirable to me if that's how it's implemented. (I'm not sure where to look for the implementation off the top of my head.)

This is the implementation: return !t || t == 1;

Thanks! I remembered after I posted the last comment that this was a change to Source/WTF/wtf/EnumTraits.h in
Bug 190731
.
