There are lies, damn lies, and statistics. May I remind you that you started counting packages as argument?
It was not an argument, it was an attempt to answer the question asked - "when is an FPU really needed" - the answer is not "never".
Frankly, I can only tell you from my personal use case that only a minority of programs profits from the FPU, and an even smaller amount really requires it. I cannot tell you if that's 0.2%, 1% or 5%, but it's all in the same order of magnitude, namely "negligible".
It all depends on what software you install and use, and how you use them - the number of binaries is rather irrelevant, what is relevant is _what_ binaries, and whether the user sees a need to use those.
For example - do you want to use TV-paint? Then you need FPU.
Is TV-paint negligible? Maybe, for "most users". But so what.
