Well, it is my understanding that while Excel provides a fast fourier
transform in an add-on datapack, the proposal goes well beyond that. I
have found that sometimes implementing a function shows the true
problems that one doesn't see when one is just writing a specs. So I
would feel much more comfortable if we could _first_ see it implemented
before adding it to the openformula specifications.
