Currently NativeAOT's ComWrapper managed object wrapper supports being created with the CreateComInterfaceFlags.TrackerSupport flag. This causes the wrapper to implement IReferenceTrackerTarget.

What is missing is an implementation of IReferenceTrackerHost. Supporting IReferenceTrackerHost would enable tighter integreation between the .NET garbage collector and the unmanaged runtime. When implementing this, inspiration can be taken from CoreCLR's implementation.

This tracking issue captures some of the conversation from #85087
