I think there are decent workarounds but it is still quite time consuming and error prone for me to keep up with everything.
I wasn't aware notifications were "broke" or working any differently, I guess that would be a big deal though.
I was thinking the same thing with the followers/following tracking unread posts/time visited, problem is as far as I'm aware none of that type of data is tracked.
