The reason is that we consider data leaks between pools as security issues so I don't think we can have some feature that is actually causing a security issue. It will be a bit tricky to decide what to do if this passes in the current form because we would probably need to apply security fix and disable it. If you really want to have it enabled, we would need to explicitly state in the policy and docs that pool boundary is no longer considered as a security boundary which would be quite problematic for some shared hosting that rely on it. Maybe the solution would be to allow it only if there is one pool enabled. Kind regards, Jakub
