 Replying to [comment:2 cypherpunks]:
 > Whoa, so are you in business of backporting sandbox level 2? Then for
 other platforms too. Also are you going to do cherry-picking from the
 trunk?

 We are in the business of getting content sandboxing on Linux going at
 all. ESR 52 does not have that by default. We are better off on macOS and
 we have #16010 for Windows. Once we have content sandboxing running on all
 supported platforms we can think about tightening the policies by
 backporting (more) patches.
