Currently on SO, a question can be closed and then edited by its original author. Potentially, this editing can change the context and even spur a reopening of the question.
Is there is value in letting the closed question stand as it first was (thus forcing the OP to ask a new question) rather than transforming the one that was closed.
If the question changes sufficiently to no longer be close-worthy then it's a different question.
If comments were left regarding the original form of the question, then they would become confusing and irrelevant following the edit.
An unedited, closed question could provide valuable guidance on question-asking for those following behind.
