politicians may choose to do just that, waiting till the worst bits have faded from memory. But I can't see why other people shouldn't be able to carry out a continuing assessment of how different approaches - Swedish, Australian, Taiwanese, US and British for example - are panning out.
And if the outcome is that those who acted quickest did best - well, that's looked the likeliest outcome all along. And it can inform official responses right now, for example in preparing for the possibility of a second wave of infection.
