It came from the top of Azure and for Azure only. Specifically the mandate was for all new code that cannot use a GC i.e. no more new C or C++ specifically.
I think the CTO was very public about that at RustCon and other places where he spoke.
The examples he gave were contrived, though, mostly tiny bits of old GDI code rewritten in Rust as success stories to justify his mandate. Not convincing at all.
Azure node software can be written in Rust, C, or C++ it really does not matter.
What matters is who writes it as it should be seen as “OS-level” code requiring the same focus as actual OS code given the criticality, therefore should probably be made by the Core OS folks themselves.
