No, I did it that way intentionally, with the thought that we might add
back return code zero (or other return codes) in the future. If we go
with bool then sensible expansion is impossible, or at least ugly.
(I think it was you that objected to 0/1/2 in the first place, no?)

This assumption seems unproven to me, and even if it were,
it doesn't mean we will never have any other exit codes.

I'm unconvinced this is a good thing either.
