Perhaps someone will know whether the seed pods develop better or that the seeds are more viable if left on a rooted plant. I had eight seed pods (four varieties) that were on cuttings, donated to me last November. I was told to graft those cuttings (with seed pods) but none of the grafts "took". I think I ended up losing all four cuttings and three of the four root-stock plants as well. Those grafted cuttings were kept in my "Everything Else" greenhouse. The pods seemed to mature/dry over those fall/winter months and I have seedlings from those pods' seeds, germinated in May/June.
