(I should probably change the subject, but this is just a quick interlude and hopefully won't spawn a long conversation.) Do you really think that's bizarre? I always think of filter taps being naturally expressed in the time domain. But maybe that's just a limitation of my background. In the constructor of the fft filter block we do the FFT to convert them. Since all of our algorithms return the taps in the time domain, it makes sense to me to handle both filters the same.
