the problem is that Rust sucks the air out of the programming ecosystem because its proponents throw down the safety hammer, and research on other safe alternatives is slow. we do have an alternative low level memory safe language (Ada) but for whatever reason that's a nonstarter... there's no compelling reason that rust has to be the only way to achieve memory safety (much less in the OS domain where for example you don't have malloc/free so rust's default heap allocation can't be trivially used).
it might do to wait until some other memory safe alternative appears.
