A good practice is to deliver source code automatically with the binary release, even if you plan on modifying the source code shortly after that. The reason is that you won't lose the source code, since it will be in a module archive. You can always contact the module archive owner to put the beautified source code in the archive later on.
I can only remember one module for whom this would have been helpful: deskfolders, but hey, prudence precaution, you know :P
