This allows the usage of this PR from eko NNPDF/eko#415
Which makes (in my computer) a 100 replica fit evolve in ~2 minutes (instead of ~20m) (which would make #2168 unnecessary) but requires also NNPDF/eko#417
So I'm leaving this PR here and depending on how things work out in eko we will merge this directly or #2168 first and then revert it when we merge this.
