Yes, but this is an exceptional situation. We normally don't add new
APIs in bugfix versions. We'll have to live with it.

It's still incredibly ugly. Besides, code written for 2.7.1 might not
"blow up" with 2.7, but it will still have different behaviour.
If you are using the new parameter, it's because you *need* it, hence
different behaviour will be unacceptable; therefore, better to raise an
error as the API change proposal does.
