PencilKit clarifications

Please can someone from Apple tell me what is going on with PencilKit? I want to include it in my app that has a minimum deployment target of iOS 11. Initially it wouldn't upload to the App Store, I'm assuming because of issue 53811027 in the release notes. So now iOS 13.1 has been released, can we release it yet? There are rumours going round that we can only use PencilKit with apps that have minimum deployment targets of iOS 13.1. Is this true? If so why? That doesn't make sense!
