I recently made a revision to this question.
It was a substantial revision because the OP had posted an answer to the question that should have been an edit to the question. I flagged that answer and it was removed really quickly but not before I'd copied and pasted the text into my edit view. So my revision included the OP's edit.
I checked in on the review status of my revision and saw that one of the reviewers rejected it with this note
This edit changes too much in the original post; the original meaning or intent of the post would be lost.
As I don't have enough points to review edits or flags, I don't know if the reviewer was able to see that I had incorporated the OP's deleted answer in my edit. I wanted to be able to tell the reviewer that, but there is no way to respond to a reviewer.
Now, I understand that allowing everyone to respond to every review might get a little crazy and mods have a lot to deal with already, but maybe once a user has a certain number of points and/or reviews under their belt, allow an option to respond to a "Rejected" review? Or open up a specific Chat room for that purpose? Again, only available with a certain number of points/accepted reviews.
