ABI compatibility. However, as I understand it, not many backward ABI
incompatible changes in Numpy are not expected in future.

If they were, I note that if you work in the same environment, you can
push repeated compilation times to zero compared to the time it takes to
run tests in a way that requires less configuration, by enabling
ccache/f90cache.
