You are being pedantic here; this stance doesn't survive contact with the real world. The fact that Rust's language reference is not complete/up to date, doesn't mean that Rust is defined _just_ by "whatever the compiler does." There are community-wide accepted documents (the reference, Rustonomicon, RFCs, and more informally, Language/Compiler team meeting notes/comments that reflect their consensus about the semantics) how Rust _ought_ to work.
