Reminds me of DAS. Which didn't break any rules so to speak, but FIA thought Merc had put enough time into researching it that other teams that implemented it would perpetually lag behind until it was standardized. They let it ride for the year Merc introduced it but banned it after that. Personally think that was a bad idea since the other teams would have caught up by now and it would have made racing more interesting. They accepted it because it was manual and didn't "break rules." If the brake thing RB was doing is real, then that's automatic, which could have been where contention came in.
