Sorry for the delayed response.

Sure, but it's nowhere near as thorough. Some ads are served by domains you probably wouldn't want to blacklist, and otherwise you may want to block specific page elements like your in-browser adblocker does (or should).

If you MITM your own traffic you can do that kind of matching to block individual requests. Does that make sense? I had a raspberry pi running pihole for quite a while and when something broke with it I just gave up on it as I didn't feel it was buying me that much.
