+  The Swift team is tracking COM interop with [swiftlang/swift#84056](https://github.com/swiftlang/swift/issues/84056).

 - Adding support for managed (.NET or C#) image types. Support for managed types
   on Windows would first require a new Swift/.NET or Swift/C# interop feature
   and is therefore beyond the scope of this proposal.
 
+- Adding support for WinRT image types. WinRT is a thin wrapper around COM and
+  has C++ and .NET projections, neither of which are readily accessible from
+  Swift. It may be possible to add support for WinRT image types if COM interop
+  is implemented.

 - Adding support for other platforms. See [ST-0014](https://github.com/swiftlang/swift-evolution/blob/main/proposals/testing/0014-image-attachments-in-swift-testing-apple-platforms.md#future-directions)
   for further discussion about supporting additional platforms.
