When using Marshal.GetObjectForNativeVariant, this gives a warning:

warning CS0618: 'Marshal.GetObjectForNativeVariant(IntPtr)' is obsolete: 'GetObjectForNativeVariant(IntPtr) may be unavailable in future releases.'

We heavily rely on being able to interop with variants (which actually works just fine in Core 3 Preview 2). Would be happy to move to a different technique, however the warning doesn't contain a suggested way to do things right. Does the obsoletion make sense? What's the future proof way to marshal variants then?
