Why is LC Task not supported with .NET Core?

[JanThomas118]

I am talking about the following Code snippet. https://github.com/dotnet/msbuild/blob/main/src/Tasks/LC.cs#L94-L107

This prevents handling of licx files for .net framework applications with dotnet build. Instead msbuild.exe must be used.
This is annoying because the UX of dotnet build is much nicer and in my measurements it is considerably faster. (Even if msbuild.exe /m is used)
I understand that lc.exe is obviously not supported on non-windows platforms and that there is no intention of porting it.
But this Task is just calling an external executable and should be able to run on .net-core on windows.

In my head the method would look something like this and the preprocessor directive would be removed:

	bool isWindows = System.Runtime.InteropServices.RuntimeInformation.IsOSPlatform(OSPlatform.Windows);
	if (isWindows)
		return base.Execute();
	Log.LogErrorWithCodeFromResources("TaskRequiresFrameworkFailure", nameof(LC));
	return false;

I did read trough #1462 and honestly did find a convincing answer.
I did ask this on the msbuild repo before but they told me that they don't really own the code: dotnet/msbuild#11511
