Previously the ApplyPolicy logic was to use the filters field set, and ignore the policy field set. But this caused problems, as a filter couldn't express that it was able to work on all valid types. This caused certain complex types Vec of Vec's to fail to work properly, and would cause compile use code paths that would never be valid for a given policy.
