In the last day, I've noticed a few edits on questions that have been closed for a rather long time (example 1, example 2). While some closed questions can be simply reworded or rephrased to become on-topic and reopenable, the questions I've seen seem like they will never fall into that category.
By editing these questions, we bump off-topic questions back to the front page, wasting space for questions that are actually good questions. Is there a reason I'm missing for why we should be editing these questions?
Edit So now that we can reject suggested edits for custom reasons, is something along the lines of @Raven's "Do not disturb the dead" a reasonable response?
