This question was recently edited.
The edit changed the meaning of the question: so, existing answers no longer make sense (they are no longer an answer to the question).
Is this a problem, should we roll back (undo) the edit to the question?
I know that some other SE sites don't permit this kind of late edit to a question (I'm thinking of, for example, About answer-invalidating edits on CodeReview.SE).
If you do permit the edit, should we delete the answers?
It's because we shouldn't delete the answers that I think the edit to the question is a type of vandalism.
If the OP wants to ask that new question, they can ask it as a new question.
