It's not the worst thing in the world, either -- sometimes one wants a
bit of the C structures layout from the .pxd file to use the array
interface without actually calling any of the numpy C API. Thus,
occasionally, calling import_array() would be a (probably very minor)
waste. However, this appears to be a completely moot point now...
