Its unfortunate that the proposed realms is still just a proposal. Even still I've heard many arguments that since the method of isolation lives inside JS it cannot be expected to be entirely secure and you would be much better off relying on OS level security primitives, a point that comments I've read so far completely glosses over. I'd love for someone to prove me wrong that this is air tight so we can champion realms at my work.

POLA is good to live by regardless if it can be implemented.
