Should questions or answers on questions that are closed be edited, even if the question is closed and the edit does not change anything about the reason it's closed?
Example: This answer was just edited, which I saw in the review queue. It certainly improves the answer, but since the answer doesn't really have to exist on SE at all (because the question is off-topic), should this edit be made?
In my understanding, the only reason that the edit option for a closed question is not greyed out is so that it can be edited to make it comply with the SE rules.
