In the past, I added a lot of pins with the "information" tag to mark a former border checkpoint within Schengen areas. I haven't been maintaining that, because I really do not think it is relevant. 
The "border control" tag isn't relevant within the Schengen zone. Yes, those are state borders, but if someone tries to navigate, let's say, between Eastern Hungary and Thessaloniki, Greece, they will always have the option to drive through Serbia and Macedonia (= with border controls) or Romania and Bulgaria (without border controls). The fact that someone forgot to remove tags from Croatia is still not an argument ;) Nowadays' countries within that area are the equivalent of regions in other countries :)
