I should have said I think you are operating under false assumptions, are making invalid comparisons, and are therefore drawing unwarranted conclusions.

I think you might be confused about what Rust offers and from where Rust's safety is derived. There is no "safe subset" of Rust. As far as I know, that is a nonsense phrase.

I think nonsense is rather too strong: Rust-banning-`unsafe` is a subset of the full language accepted by the compiler, and is safe. It isn't rare that people talk about the subset of Rust ignoring `unsafe`.
