With respect to this meta post on SO, Are answers which drip feed information in subsequent comments acceptable?, wouldn't it be a useful feature to be able to also contact the reviewers of both accepted and rejected suggested edits, via the comments, using the
@, in a similar way that successful editors are able to be reached (see this answer to How do comment @replies work?).
This way reviewers who have misguidedly either accepted or rejected edits could be informed. As it stands, if I understand correctly, such reviewers are not notified in any way and will be unaware of their mistakes, and will continue to do the same in future, without having any guidance, or correction - unless they happen to come across a meta post raising the issue relating to a specific suggested edit (assuming that such a meta post has been posted).
Admittedly, it could open such reviewers up to complaints from (unjustly) aggrieved editors, who have had a bad suggested edit (rightfully) rejected.
In response to Nicol's answer below, given the ephemeral nature of comments, the comment[s] would not necessarily need to hang around for long.
As a case in point, I recently suggested an edit (which was to add code formatting to a question which was in the First Post review queue). This edit took two hours to be approved, yet in the meanwhile the question was closed (as off-topic) one hour after my suggestion - so it appeared as if I had edited a question that had been put on hold.
I then received a comment cordially telling me not to edit closed/on-hold question, and pointed to the meta post relating to not to do so. I replied and pointed out that the suggestion had taken a long time to be approved, and that the post had not be on hold when I had made the edit suggestion.
I received an apology and then the comments were tidied up and removed by both myself and the other chap.
