> ban Epic from doing other lines of business via macOS tools (e.g. Unreal Engine development) seemed excessive compared to other app bans

No, if you try to smuggle forbidden features through the approval process by hiding them and only enabling them after the app is published your developer account will be terminated immediately. This is clearly documented and Epic knew this up front.

Getting the chance to revert the changes before the account is terminated is what sets apart Epic from most other developers, like people that changed their apps to full emulators after it got approved like what looked like a single game.
