We shouldn't move its > functionality to `file-attributes'. access-file is different: it signals an error if you cannot access (actually, read) a file, and if you cannot access the file because you cannot search its parent directory then that's simply another reason that you cannot access the file. In contrast, a predicate like file-exists-p is supposed to tell you whether the file exists regardless of whether you can access it.
