Let's say it's not impossible that someone uses NumPy and Cython without any accelerated C level connection between the two, but it's rather unlikely, given that Cython already has all dependencies that this connection would require as well, except for the NumPy header files. So I would suggest to make the automatic override the default for any module for which a .pxd file with the same fully qualified name is found in the search path, and to require users to explicitly disable this feature for a given module using a module level (or external) compiler directive if they feel like getting slower code (or working around a bug or whatever). Anyway, given that this feature isn't even implemented yet, it may appear a bit premature to discuss these details.
