There was a few championships won because someone crashed out in the past. It happens. Part of being champion is not crashing, so I see no hollow victory for anyone, even if MM is out the whole season.
Something else is, while MM made a mockery of them during 2019, we have no idea how well he would have done this year. The Ducatis, Suzukis and KTMs seem to have made a nice jump in performance, while Honda seems to have gone the other way. It may well have been MM's season to struggle this year.
