It's great that you want to take the time to leave a lengthy review. But you're scarce - most people don't want to do that. The review tabs, if they're created, would mostly be blank.
Also the ratings / review section are currently not in the control of developers and there are no checks and balances. (Anybody can rate / review my game whether they've played it or not - and that happens.)
Developers can manage the comments. So if someone leaves a helpful comment, we can respond to it, answer questions etc. If someone leaves a comment that is spam or irrelevant we can delete it. That's important.
