This as an optional item would be great. However, there are various free and paid platforms that support this. Google, Trustpilot, etc. As long as those platforms aren't too intrusive, an integration with a few top ones would be great if not an internal system.

Not really interested in this. This can make already difficult products even more difficult to sell. A sirloin steak is never going to taste like a ribeye, but someone might think it should, giving it a poor rating.

As long as we had the opportunity to moderate the reviews or comment on them as well

This would be cool
