Part of this infrastructure does rely on `AllPermission` and its `PermissionCollection`. I don't see a reason to deprecate `AllPermission` before deprecating `Permission` itself.

Can you elaborate or give an example/pointer to code on how it uses `AllPermission` w/o the corresponding SM APIs and infrastructure (policy files, `AccessController`, etc)?
