open extension do not exist either. :)

And it bums me to have to explicitly type private on ever single member to achieve the same result as I can with any other access level.
In the same way that we need to be explicit about open in extension members or public in public type members; the lowest access version of scope private needs to also be explicit in private extension members and top level private concrete type members.
The premise of 169 was never about creating a new version of scope private that could only be used in extensions. It just relaxed the rules for explicit private extension members.
