But all other built-in constants have an initial capital letter: None, NotImplemented, Ellipsis, ...

That certainly doesn't apply generally to all of Python: sys.version, sys.byteorder, sys.platform, sys.maxunicode, string.digits, string.other_constant_strings.

Those you bring up are conceptually "objects", in the sense that you want to be aware of identity, whereas true and false are conceptually "values", in the sense that you never care about their identity, only about their state.
