Yes it would. The primary purpose of this annotation is to *capture design intent*. It is not required. The compiler will help you enforce the design intent if you provide it. The compiler will not synthesize this annotation, since that would be guessing at the design intent. It is possible to create classfiles that subvert the design intent.
The point about other languages was simply to point out that the universe of tools that might usefully use this design intent is bigger than sometimes assumed.
