I think this is a very unique approach and something most reviewers don't see like you do, otherwise they wouldn't speak to the author directly in their reviews, like so many do.
I write reviews to communicate with an author, give them feedback or encourage them. Feedback as in telling them what I like and what I didn't like, in a polite way of course. I also write for the readers, naturally, if there are readers who actually read reviews before they start to read the story. I never do that because I want make up my own mind, like to learn what is behind an intriuging title, or just because I'm curious.
As an author reading about mistakes I made, or I might have made in the eyes of a reviewer doesn't make me happy. If it is justified, I repair it, if it isn't justified I take in a deep breath and try to discuss it with said reviewer. The perks of writing in/for a forum or community.
Almost every author I know gets something out of reviews, whether it was the intention of the reviewer or not, so they are for them/us too.
