The point of the Unsafe Rust is the containment of relative "unsafeness" (that is, however, not equivalent to C/C++'s UB [1]) within a certain boundary. Having less things to audit surely helps.
That said, of course Rust is not a panacea for memory and synchronization bugs. Rust helps a lot but does not fully solve logical memory leaks and deadlocks for example.
