I don't see how this addresses David's argument.
While being the "fastest BSD-compatible FFT for power of 2 problem
sizes" achieves a certain Pareto optimality, wouldn't it be more
productive to provide better support for actively maintained libraries
that are faster and more general?
How large is the djbfft + SciPy user base?
