It pisses me off to no end that you can't build those applications, but this stuff isn't caught by their filter.
I think that's a false equivalence. The devil is in the details with large projects like this.

Been receiving a steady stream of notification emails from Apple about them, and some have already been taken off the store as a result of my inaction. Not all at the same time mind you - about a week or so between apps.
They are serious about the cleanup, but I expect it will take time to go through the millions of apps on the store.
For most of them, it was because I had never updated the screen sizes or anything to suit the newer iOS devices, plus used old SDK calls or Ad plugins etc.
Then I got another email about two weeks before. At the same time, the app were flagged on my iTunes Account, and I received 2 notifications (2 weeks before, and on the day of removal) via the iTunes Connect app that I have on my phone.
There was also an email a few months back explaining that they would be conducting this clean up in Sep/Oct.
All up, I believe it was plenty of warning. I just couldn't be bothered to make the changes as the apps were pretty much dead anyway, and there were too many competitive ones that were far better, so I let them kill them off.
