FFT was added to that list due to feature requests to boost.math, see:
https://github.com/boostorg/math/issues/303

I agree that writing FFT which supports all multiprecision types is a
tremendous task. But if it's not in GSoC it has a really hard chance
of being completed, ever. So maybe the right approach is to split this
task into several smaller sub-tasks?

Maybe first make a GSoC project for 1D FFT which works with math and
all multiprecision and has speed comparable with libfftw when using
double type (and is correctly templatized and designed, etc ;)

and uses boost.math code to jump-start.
