I kind of like this option because it's consistent with `typeset -n` meaning "operate directly on the ref variable", and declare together with assignment meaning "redefine the variable" in most cases. I'm not so sure a warning is needed since replacing the variable with a new definition would be the usual thing to do with any other attributes, and the identifier literals used within one scope should be under control.
