Motivating example: This suggested edit corrects a clear error in an answer, but the error is central to the answer's premise—it answers a question about sitting presidents as litigants, and the error is that the litigant was not a sitting president at the time of the lawsuit, but in fact the president-elect.
On Stack Overflow, we tend to reject edits that substantively change an answer, even if the original answer was wrong, but it's unclear if the same policy makes sense here.
How should such suggestions be handled?
