If that's all it would take, then definitely go for it. I'm not
sure "breaking people's code" is the right image, though. It's more
like "forcing people to upgrade" to take advantage of new features.
Improvements to the encapsulation of the numpy C-API are definitely
welcome. They have come a long way from their beginnings in Numeric
already due to the efforts of you and David Cooke (and I'm sure others
I'm not as aware of).
The problem I have with spending time on it though is that there is
still more implementation work to finish on the datetime functionality
to complete the NEP implementation. Naturally, I'd like to see
those improvements made first. But, time-spent is usually a function
of how much time it takes to "get-in" to the code, so I won't try to
distract you if you have a clear idea about how to proceed.
