Google Review Feed not following policy

I decided to try your plugin to generate a Google Reviews feed to give to Google. Many different things are made incorrectly:

#1 If I have variation listings with reviews, you create a copy of the review for every single variation – so I end up with duplicate reviews equal to the number of variations. This is against Google’s feed xml schema policy, they require you to make one review and add multiple ‘products’ under that one review (see here – https://developers.google.com/product-review-feeds/schema#review)

#2 Why do I not get given the option not to include <title> for the reviews? This is optional

#3 For variations, I should be given the option to make the review_url type “group”, instead of defaulting to “singleton” with no ability to change it

#4 “reviewer_id” is option in the schema, but if it is included it must be unique to each reviewer. I am not given any option not to include this, but it defaults to 0 (zero) for every reviewer defeating the purpose entirely
