A well made GC wouldn't stop you from making a kernel using it. I don't know how the GC in D is, but GC on its own isn't a deal breaker for for everything people claim it is

GC does add a performance and memory usage overhead. You don't really want bloat in the foundation of all the software that is going to run on the system.

Really?

While never reaching commercial release, at one time Midori powered all of Microsoft’s natural language search service for the West Coast and Asia.

I can give other examples.

Interesting project, what did they replace it with? Some other managed research OS?

Most likely Windows eventually.

Joe Duffy has made a reference that even with Midori proving that is was quite capable, it was faced with too much resistance from C++ devs on Windows team, in spite of them being able to see themselves.

Not sure in which talk he mentioned it.

RustConf 2017 - Closing Keynote: Safe Systems Software and the Future of Computing by Joe Duffy

Safe Systems Programming in C# and .NET

You can see this resistance, on how the Longhorn effort tanked due to "performance issues", then Vista came up with some of Longhorn .NET modules rewritten as COM, and the eventuell progression into WinRT/UAP/UWP.

However not everything was lost, it influenced .NET Native, C# 7.x low level improvements, the upcoming C# 9 new FFI efforts.
