After seeing that this edit suggestion got rejected because it "deviates from the original intent of the post", I realized that I have no idea why or how an edit could change the sense a post makes.
What causes edits to do so on PPCG?
What Timmy said in his comment is exactly right:
this edit should be rejected since we're not sure exactly what the original intent was.
I can't speak for the other user who voted to reject the edit, but that's why I rejected it. This was a fairly drastic change to the post (including the voice in which the task is described) and since the post wasn't entirely clear in its intent, it wouldn't be appropriate to modify it in this way; it should be the job of the challenge author to clarify their own intent, particularly when the information they're providing in comments contradicts what's currently in the post.
In general, edits to questions are appropriate if they clarify wording without making assumptions about the OP's intent or if they greatly enhance readability through formatting improvements.
