While I would tend to agree with you in theory - I don't think we should make it the default - at least not without a LOT of lead time. There's a surprising amount of code relying on the current behavior that I think the best course is to enable this option, and change the docs to steer users in this direction.
For users jumping from 2.x into 3.x, I think the less surprises they have the better, and changing the default behavior of the stdlib module in this was would qualify as surprising.
