Description
It seems like there's no warning from the COM generator when declaring a P/Invoke returning a COM object through an interface that's using ComInterfaceOptions.ManagedObjectWrapper, despite the fact the marshalling will never possibly work.

Reproduction Steps
Paste the following code and build:
public static partial class DXGI1_3
{
[LibraryImport("dxgi")]
public static partial void CreateDXGIFactory2(uint flags, in Guid riid, out IDXGIFactory6 ppFactory);
}
[Guid("C1B6694F-FF09-44A9-B03C-77900A0A1D17")]
[InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
[GeneratedComInterface(Options = ComInterfaceOptions.ManagedObjectWrapper)]
public partial interface IDXGIFactory6
{
}Expected behavior
Some warning on the [LibraryImport] parameter, saying the interface is using invalid marshalling options.
Actual behavior
No warning, but the generated code will just never work.
