Half of the challenge is how brave you are over the exit kerbs at tracks like the Red Bull Ring, and though that challenge is less now that it used to be when the cars weren't quite as planted, it's still nice to see drivers being tested.
The way things are going there's no penalty for bailing out of a corner and just skipping over a huge tarmac run-off. There needs to be something in place which punishes drivers and just lets them get away with what they can, such as the different approaches for the old La Source. Perhaps some grass immediately after the corner, so if they do go off they have to skip across some grass. That's why the Red Bull Ring is/was good - turn 1 for example they can monster the kerbs, but go to far and you'll lose time as you have to either abort to the grass or wrestle the car back onto the track. You don't need gravel for that.
