It appears this would block pretty much all the major analytics tracking cookies (e.g. Google analytics, mixpanel, etc.) based on the linked Disconnect list, https://disconnect.me/trackerprotection .

While I realize that's kind of the point, in my mind there is somewhat of a difference between "the site I'm on is tracking me to figure out how I use their site" vs. "any site I visit is essentially aggregated data because all the sites use the same major trackers and ad networks". I wonder if the big analytics companies will need to change their business model, or at least their tech, to account for these kinds of changes.
