I'm not exactly sure how useful it will be to have the Pathauto pattern for files defaulted to file/[file:name] especially since when you install the module, [file:name] by default is the basename of the file on the system. Not exactly the most useful. Also this can create conflicts if I named a file '1' so that now the alias file/1 overrides the system path file/1.
Pathauto integration is good and useful, but I don't agree that it's useful enabled by default. Discuss?
