Yes, please take a step back from what we have right now because it
isn't very good. It's a general policy decision / enforcement problem
and even the policies may change dynamically. Having a central
authority doesn't automatically solve any of that and it'd be most
likely as limited as existing solutions at the beginning but it allows
for future improvements unlike scattering the solution all over the
place which just digs the hole deeper.
