But I wonder if you could use the modified version the author posted with AltStore (or plain old Xcode signing) to get virtualization support on the M1 iPads which don't require kernel modifications. I'd pay $100 a year for a developer account if I knew I could run macOS and Linux at near native speed on my iPad.

Does anyone know if you can install apps that use private entitlements without a jailbreak if you compile/sign them yourself?
