Oculus Integration (from AssetStore) does not work with Oculus Loader
As per fogbugz Case 1195296, Oculus Integration collides with XR Management Package - type or namespace name 'XRDisplaySubsystem' could not be found. Having both the Oculus Integration utilities from the asset store in my project and adding XR Managament package from Package manager causes this error. I am aware that the announcement thread for XR Management does mention they currently aren't supported together: https://forum.unity.com/threads/xr-plugins-and-subsystems.693463/
This is even more of an issue as most apps on the Oculus Quest require FFR (Fixed Foveated Rendering) to be active at some level to increase performance or reduce the strain on the device. Without the Oculus Integration, we are unable to activate FFR while using XR Management.
According to the XR Graphics Team Lead 'Daves' on the forum here, work is being done to improve FFR support in Unity, will the option to enable it be exposed through XR Management somehow so we don't need to import Oculus Integration from the Asset Store to enable it? https://forum.unity.com/threads/xr-plugins-and-subsystems.693463/page-2#post-5066672
