Python's booleans being ints is a remnant of history. I agree it would be
better for True and False to be unrelated to 1 and 0.
The conversion of 0 to "0" is because JSON can only use strings for keys in
objects. It might be better for dumps to fail if a non-string key is
encountered, but I'm not sure.
