Improvement to the AppStore Review system

Public responding has problems, private responding too.

How about a different approach:
Developers (perhaps users too?) can tap a “encourage user to contact” button next to reviews. Thereafter, the reviewer would get an email with a standard apple mail: “developer x suggests you contact his support at y about your review”. Furthermore, there is a standard apple reply (“the developer suggested to contact support”) below the review as “a response”.
