Er... we have the 2010 editor on UCP now. And we have social activity to see our comments, wall messages, and posts.

I don't see why you're still complaining, unless you're one of those people that uses source editor on legacy and is having to put up with keeping the 2017 editor enabled on UCP so it doesn't interfere with your legacy settings.
