Sorry, that didn't come across with the intended tone :)

I agree that this could be out of scope for the random module but I wanted to make sure the reasons were considered.

Reading between the lines I get the impression that you'd both be happier with it if the algorithm was exact (rather than using fp). That would at least give the possibility for it to be used internally by e.g. sample/choice if there was a benefit for some cases.
