The announcement indicates that notarization for iOS platforms will include human review. They are basically dividing the App Store review process in half, with the platform safety side (for all apps) and the content/quality side (only for App Store).

How else are they gonna obligate developers to pay the core fee then.

Once tooling catches up, in theory, developers don't have a contractual relationship with apple anymore, except to get notarized.

The devices belong to the users apple sold the hardware and licensed the software to them not app developers. They could charge the users but obviously this would be a terrible idea.

Getting notarized will either directly require payment of the platform fee or will force the use of the official tools which will mandate that.

no it says it includes “human review”
