I have an review in my queue where the only change was to add a block of code as an example. My initial reaction was to reject it but none of the rejection reasons seemed appropriate.
In general, is this something that is considered allowable? If not what reason should be used to reject it?
Gnat pointed to the specific question in the comments but I kind of want to talk about a more general case. The reason I considered choosing is "This edit deviates from the original intent of the post. Even edits that must make drastic changes should strive to preserve the goals of the post's owner."
What made me stop is that that reason suggests that it's OK to make drastic changes (such as adding code examples) as long as they are consistent with the author's intent. I didn't yet take the time to evaluate whether that code is consistent but assume for a second that they are. If, hypothetically, the additional code was a perfect example of what the author suggested, would it be OK? In other words is there line where a change is can be considered too drastic?
