Most user-specific stats are specifically designed to only be visible to that user, including your helpful flags count. Only website, location, age, member for, seen, and profile views are visible to the public. Your email, real name, visited stats, and helpful flags are not shown to other users.
I really don't see any need to add number of reviews to the profile page, as that's not really a helpful number to anyone viewing your profile. The only place I can see it being of any real use is in an election. The SE team has also made no indication yet that those review stats will even be carried over to the new review panel, but have confirmed that there will be some sort of stats summary for the entire new review panel at some point, and that the existing badge progress indicators will be integrated into the panel.
Anyone can already see the number of revisions you've made simply by viewing your activity history.
