It's a bit early to decide on that I think.
One of the commentators, a vastly experienced F1 race engineer went out on track after the race and was able to point out the problem (or potential problem...if you prefer).
A raised (1") straight sharp edge on the back of the kerb is not helpful to safety, and can easily be rectified.
The inside edge of a tyre running along that is likely to get cut....especially if there is a weakness in that part of the sidewall of the tyre, as it appears MAY be possible with the Pirellis currently being used.
Four out of the 22 cars running those tyres and running over that kerb suffered blow-outs...all affecting the left-hand rear tyre wall.
None of the other classes of race cars use those tyres.
