It would be interesting to see if this gets adopted in something like Tails where security is the priority focus.
Tails apparently doesn't even have time to patch grsec/pax so unlikely. It took them almost a year to add macchanger on boot even, they spend all their available time patching the flood of bugs due to cramming their distro full of userland tools like video editing software.
Sounds like their efforts would be better spent on a ChromeOS-like OS that's only a Tor (or Astoria) browser at its core.
