If you, me and anyone who's spent more than a few hours with Django split settings.py into multiple files (and heavily modify it), why is it still shipped as one monolithic file? Isn't the framework supposed to make our lives easier? Splitting settings into multiple files is the least of my problems (nowadays it is not a problem at all). The biggest problem I have with it is that it is global, which means I cannot safely modify it at runtime.
