Revisionism or not, midi-chlorians are a bad idea. And the fact this is never mentioned by Ben or Yoda in the OT shows it was a useless idea to explain what the Force was. That being said, it’s not even clear what midi-bullshit really are : biological side effect of being strong with the Force or cells that give one’s Force sensitivity ?
According to the article by Rinzler (that was mentioned earlier) they are energy sensitive organism that connect your cells to the Force. So it has more to do with how a Jedi connects to the Force. So it has to do with Force sensitivity.
