I don't think knee jerk reactions are needed, although at the risk of stating the obvious it would be right for this to be followed by some expert consideration of lessons learnable. Comments around the lack of need to push vintage airframes though aerobatics (it's enough for people to see them displayed) and eg "start high and fly down" sound measured and sensible to me. But hopefully better minds than mine will draw some sound conclusions, based on a good and dispassionate view of the facts.
