Well - it'll still potentially affect your main race if you absolutely smash your car to pieces and your team spend all night trying to rebuild it. (And I think repair costs are still counted in budget cap, so you also don't want your drivers costing you money for minimal championship benefit)
The other perspective is that now it doesn't affect your main race in terms of positioning etc. and the points being dished out aren't particularly big, I don't think we'll see as many people going for it. If you end up at the back of the Sprint grid, there's not really any reward/incentive to do what Lewis did in Sao Paolo before and rip your way to the front, as it won't benefit your main race, you'll risk crashes, you'll put wear on the engine and chances are you won't reach the (meagre) points paying positions either.
I think this places a lot more reliance on the drivers just wanting to race and hoping the teams don't reign them in too much, as the rewards don't seem particularly good vs the risks now.
