Yeah. I don't see any practical relevance today, but allowing to retrieve any attribute of these hidden files (fdinfo and hidden files included) is a good thing that the flat nature of the current fdinfo inteface makes difficult. I'd argue that many current uses of fdinfo could be enabled with the listxattr/getxattr inteface and would improve usablility (no need to parse the fdinfo file to skip unneeded info).
