Hand Tracking on Android with Mixed Reality OpenXR plugin deprecation warning

[halfpasttense]

I'm very confused by this deprecation warning. Does this mean we will no longer be able to use MRTK v3 on Meta Quest devices and still have functional hand tracking? Or is there some way to still use MRTK but without the Mixed Reality OpenXR plugin? I would actually prefer to use the default Unity OpenXR plugin, so that I can enable the new "Meta Hand Tracking Aim" feature (I need this to get access to the hand gesture that activates the menu button), but I have no idea how to do this in an MRTK project.
