I'd finish them out. The seeds aren't anything I would run first but could be saved as a backup. I've got some seeds from a Sin Mint Cookies plant I grew about 5 years ago that selfed a hand full of seeds. If I even need seeds or have room to run them I will. In the meantime, they are hanging out

The thing with hermies is most plants don't just do it themselves. There is usually some sort of stress trigger. I've seen it happen on the 2nd and 3rd generation of clones from the same mother plant. One clone maybe will get stressed somehow and throw a few nanners part way through flower. Usually, I just pic them off and move on with no issues.
I've also grown plants that fully showed both male and female sex parts and had to be cut so they didn't pollinate my whole garden.
One of the first grows I did was just a little closet grow, and I got males and females from some bag seed. I intentionally let them all go through their life cycles so I could FULLY observe how this plant grows from start to finish in a natural(ish) way. I think it taught my a lot about understanding the cannabis plant.
I also run hydro and don't believe in flushing
