Why is it so hard to do this? Can't we tell controllers to do a
check of permissions, and only if they can't be sure refuse to use the
requested path by default unless a config whitelist or user prompt
allows it? I think that's a lot easier to implement for controllers, and
I just don't really see the huge threat here. If you have malicious
system-wide software on your host, you lost anyway.
