Which rather contradicts your description of it as a 'known problem',

That's not really a relevant analogy. You can't 'wear a helmet' in this
case. There's no way we could have implemented the policy and 'worn a
helmet' by allowing updates to happen without the conditions of the
policy being fulfilled; that would effectively negate the policy. 

If you want to continue with the analogy, what you seem to be saying is
that we should never have implemented the policy in the first place,
which is not analogous to wearing a helmet; it's analogous to never
leaving the house just in case something hits you on the head.
