I once heard that a major problem is that you have to disable or work around Rusts safety features once you write hardware interfacing code like a os kernel
Not really. While working at the OS-level can typically require 'unsafe' operations a core tenet of writing Rust is making safe abstractions around unsafe operations. Rust's 'unsafe' mode doesn't disable all safety checks either - there are still many invariants that the Rust compiler enforces that a C compiler won't, even in an 'unsafe' block.
And even ignoring all of that, if 10% of the code needs to be written in Rust's 'unsafe' mode that means the other 90% is automatically error-checked for you, compared with 0% if you're writing C.
