I'm surprised it's hosted by the .NET Foundation. I feel the .NET Foundation operates somewhat independently from Microsoft, but there is a large alignment with what Microsoft wants. Using LLVM feels like a departure from some of the things they're working on now. Anything regarding coreclr seems to be handled with a goal of being through and through cross-platform. Because of this tools like cmake, LLVM etc are used instead of Microsoft in-house tools. Because of this, formerly closed-source tools like MSBuild are now being made open-source. It's a departure from how Microsoft traditionally have done things in the past, but it's perfectly aligned with where the .NET Foundation is currently going.
