I can help with testing and potentially PR reviewing.
On things for 3.7; back in JME 3.4 dropping jme3-vr was discussed. At the time I was strongly against but I’ve come around to that position. Any new virual reality projects ought to use OpenXR one way or another and jme3-vr is OpenVR or worse. How do we feel about deprecating everything in that module in preparation for removal in a future release?
At the time it was suggested that VR would be better supported as a seperate library and having written one I obviously now agree
