For me the update changed traction levels again (not just traction control), it's much better and so I've ran Gr3 cars without it today (only turned on counter steer to spin out less, well at least that's the theory anyway) with out much issue, before I had to use TC 2 or I'd spin all the time when accelerating.
The only issue now is braking does not seem as good as before the update but maybe that's just me.
I don't know but I've pasted a few spun cars still on track and got zero penalties so maybe you are correct but the only way you'll know for sure is when you pass one that has just been reset to track as that was 100% a penalty before.
