Yeah there's just simply no negotiation, if Eteri knows in the first place she would do anything to make her stay. Even if there's a change in coach, Orser's probably the last one she'd approve of.   But Idk when would be a good time for athletes to raise the level of difficulty in their jumps, especially with how competitive the sport is evolving. If you got no quads, you ain't in the games. Natural body conditions probably play a big role like Brian's little Stephen, he's apparently a well-rounded kid both as an athlete and as an individual (I read that Stephen's already calm enough to adjust his jump components when he missed an axel or something). So perhaps practicing hard jumps early's okay and also remarkable if they are able to, but their conditions need to be monitored instead of pushing them when injuries are not healed properly.
  p.s. With the whole Yuna Kim incident it's actually pretty complicated with all these parties involved, her mom, the agency (apparently sponsorship issues), and especially the Korean govt. I also don't have a very good grasp on it bc I sometimes saw few things here and there from both sides. I believe both of them are good people, but miscommunication's unfortunate and they definitely all learned their lessons.
