As Python is being increasingly used for data science, this use case will be increasingly common. Being able to copy generators will save a lot of work.

Keep in mind, I don't necessarily propose that generators should be fully picklable; there are obviously a number of concerns and problems there. Just being able to duplicate the generator's state within the interpreter would be enough for my use case.

Thoughts?

I also remember I wanted this feature few times in the past, I like the idea. The problem is who will implement this?

If you have time and energy, then you can just try (but beware, it may be harder that it looks).
