>> GNOME devs want the users to use drag and drop instead of the file pciker...

That's funny. Just replace the file dialog with opening the file manager. Drag and Drop. Better yet, just modify the file manager to have an option to self-close after selecting a file and a way to pass that selection to the app (using MIME types would not allow the DE to get it to the correct app in all cases).
