That is not the point. Rust prevents UB in all safe code. "Root
Pointer" being thread-safe is irrelevant: it does not prevent UB in
the rest of the code.

Given you are unaware of what Rust brings to the table, please stop
claiming your system is "way better" for the kernel.

The claim you made was that your system works for *existing* code with
a simple recompilation as an argument versus "learning Rust"... If
kernel developers need to start discriminating pointers, use smart
pointers or other annotations, or reimplement anything, then your
argument does not work anymore.
