Why? If the caller needs an expanded name, they can call 
expand-file-name themselves. Or if they need an expanded local name:

    (file-local-name (expand-file-name filename))

Aside from performance problems, this feels like an inconsistent behavior.

In any case, this didn't help because in my main scenario 
identification=localname. Whatever that means.
