All of the areas you mention as relevant to enterprise developers are things that require libraries written, potentially with APIs that lean less in the "high performance" and more on "easy to use/hard to misuse", not fundamental changes to the existing language or tooling. I personally think that the big surprise with Rust will be how flexible it can be, covering a wider range of use cases than it might look at first.

Any company that does try to work with Rust today in any vertical slightly outside of what is considered "mainstream" will likely end up having to write their own libraries for things that are already available in other languages, but that's a factor of the ecosystem's age.
