Well, if Kunos can code the base physics around the F1 data, and gradually correlate them for that for that car, then I suppose it could be useful to F1 teams eventually. It'll mean that, if nKP Retail keeps up with nKP F1, we end up with a simulation with amazing aero, tyre and other physics, even if we don't get the same data as the F1 team uses for confidentiality reasons - close guesses will be more than enough for a retail, even niche, sim.
But I'm not holding my breath!
