Not sure I understand the exact argument, but if it is just a matter of
getting default values, it is easy to share them using a common header.

At the moment, ufunc and multiarray are separate extensions. If each
depends on the other API-wise, it is an issue. If there are some
commonalities, then they can be put in a separate extensions. They are
already way too big as they are (historical reasons), we should really
fight this for maintanability.
I realize the code organization and the build stuff is a bit of a mess
at the moment, so if you have questions on that aspect, feel free to ask
clarification or help,
