i think it's ok to not have this package. I only suggested it for math because there were so many of them.

There can be so many of these as well in the future :)

how many realistically will we add?

Well, if we make RDG generic, and users can plug in their own distributions, then we won't need to add any. MLlib has 6 generators, but I can think of 3-4 more on top of that.
