I think the Access Level must follow as Guiding Principle

https://github.com/apple/swift-evolution/pull/2165/files?short_path=c413722#diff-c4137225f01736a83bc207df99b560bc7a8f1a6710b82008e95eac866bfa6032

Sometimes the access level doesn't follow the guiding principle, so I did Pull-Request the swift-evolution on Github, and if you're curious about this, I'd like you to take a look.

Please tell me if there is anything wrong. Thank you.
