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

True.

But this isn't as compelling as it might be, since None is the only one that enjoys common non-guru usage. It only counts as consistency if other people notice and remember the pattern.

The pattern people really care about is:

C99: true false C++: true false C#: true false Java: true false JavaScript: true false

(I can't find other case-sensitive languages with boolean types to compare.)

I also think repr(false) should return a randomly chosen line from an insults file. This makes the interactive prompt funnier:

1 == 1 true 1 == 17 LIAR!!!
