I think 1) is better but we need to address the 1500 failures. ~99 will go away when I patch the attributor tests, so I would suggest we first add the opt-out flag and start using it. Then we can keep track of problems in this commit and we don't have to touch 1500 files here. We should also look for patterns and write a script ;)
