Found using script:
https://gist.github.com/dims/384dea60754042f61d79233603034038

Just run using:
`find . -name .import-restrictions | xargs python ~/junk/sanitize-import-boss.py`

The removed entries are either packages that got moved/renamed/deleted
but are still not cleaned up from .import-restrictions files.
