It would make sense for MS to be interested in an existing, popular, relatively mature language that possessed many of the safety features their research languages have explored.
But Windows has been around for 35 years; it's a huge C++ codebase, so trying to turn that ship takes time. And just as you can't wholesale rewrite Linux in Rust, it'll take time to integrate Rust into the OS. I assume Azure is a bit easier since there are new services coming online all the time that aren't necessarily dependent on others. I imagine that as these safety- and performance-critical 'experiments' take off, you'll see other teams investing in a big way. (FD: I'm in the Windows org but don't have any sort of special knowledge of the decision calculus here.)
