Hey CE, I would personally be much more comfortable if I had to opt in and also it was clearly shown in the UI that this feature was "on". That way I would feel safe if I never turn it on. And if I do, then I know to check for hacks regularly.
I think you will lose votes that would vote for it if they feel worried it would create a security risk. Since its still in the discussion phase, then this would help sway a few more to vote for it imo.
