Rust addresses opaqueness and untestedness directly, by enforcing the language constraints at compile time. Rust addresses the privileged nature of the code and it's exposure directly by disallowing the most common bugs used to gain access to that privileged execution. Obscurity and diversity can both benefit from Rust's integration of Cargo and the resultant ease with which it allows for sharing common code. In short, expressing this code in an appropriate language can absolutely address and even go some way toward correcting each of those issues.
