Right.

Yes.

scipy.test() should be made to match numpy.test(). scipy.testing was a
staging ground for the nose changes in numpy, not a separate branch of
development.

For my preference, we should accept the old argument signature with a
deprecation warning but prefer the current signature. This is a little
hairy, but such is life with deprecations.

That's fine.
