Update: Page Assessments is easy enough to install, but we will have to import a lot of Wikipedia related templates to get the most efficient use of it and to some extent reverse engineer their way of doing this for our own purposes.
As for the final planned feature that is NOT related to SocialProfile stuff (I'll get to that soon), here is a rather stable extension we can use to boost our SEO.

I cannot test this for obvious reasons on a localhost wiki, but installation and use are very simple and the extension is quite stable.
