In a nutshell: I introduced a fileapi system, nearly a 1-to-1 clone of nodapi, only then for any file object. It reacts on "save", "validate", etc. And it also reacts on "form".

That hook_fileapi($file, 'form', $form) should return a form array, as well as that it passes along the existing form array. In that way modules can alter the form for a file. Anywhere. For example to turn a certain file form into a list of file forms (to allow uploading more then one file at once). Or to change a title or description. Or to remove something from the form. 

I am confident that all this no longer needs a hook, since the formapi has its own "override"  system. I think that one form of type "upload", will suffice. That type should:
* have automatically the javascript/ajax stuff with it.
* be called anywhere a module wants to call it.
* invoke the correct fileapi actions.
