Sometimes, you want .all(), sometimes .any(). It really depends on the question you are asking. Even for bool(A), there is no easy answer. In some case I want True if some elements are true, in other cases only if all elements are true. I would agree with you some years ago, but after using bool(A) = A.all(), I started noticing that it brakes my coding instead of speeding it and does not give me any benefit at all.
