I find that when asking e.g. slightly cunning DEs, some corps will make those questions close quite quickly, but reopening those questions are often very difficult, influence greatly the image of MSE that welcome maths not only in scholar uses.
I read this question as pointing to the asymmetry that a question can get closed very quickly but might take a lot more time to get reopened after being improved. Provided that both closure and reopening were appropriate, I think that is a feature not a bug. If questions get reopened immediately, askers have less incentive to get things right the first time, which is something I think we all should aspire to.
