Do you have a source for this? I'm finding it difficult to find concrete information on the new Exclave.

This is all from research done by people smarter than me; not much has been published unfortunately. A good starting point for thinking about exclaves is by looking at ARM Realms or how pKVM is designed in Android.

And 2014-ish Bromium (now HP) uXen + AX, https://www.platformsecuritysummit.com/2018/speaker/pratt/

If the "Secure Exclave" is a privileged VM (alongside iPadOS VM) on a minimal bare-metal hypervisor, does that open the door to unprivileged Linux or other user VMs safely running alongside iPadOS on iPad Pro?
