Acknowledging the past, realising/feeling bad things were done, and deciding future choice need to be better is not the same as personally feeling shame. Feeling responsible for a better future and feeling responsible for bad past decisions are independent concepts.
the trick is to combine all your uncertainty sources together. So in the worst case your numbers still have as much entropy as if you did not have the external source. And even if somebody else knows those numbers they do not know the actual numbers you are using. Of course that raises the question: if your other entropy source is good enough that you are happy in your worst case what is the benefit from some extra source of entropy? So i have argued myself into agreeing with you :) crypto is not a good use case for such a service. The wall of lavalamps mentioned above is a better solution.
The point was that this was a change that required an explicit act by parliament to happen, i.e. they made a concious choice to increase the limits. The laws did not automatically revert/change when brexit was decided.
So the timeline is:
UK as part of EU adopts the regulation into national law.
UK leaves EU, national law is unchanged by this (so regulation persists).
UK makes a new national law changing the amount of pesticide residue allowed to be higher.
Yes, thank you!
