Leave Debug on in Django for internal application
"Internal" is a relative term.  People or machines on the internal network can still be considered attackers.
I'm working on a Django project that I took over for someone else that is only used internally.  It's not deployed to a website and can only be accessed on a local network.  The previous developer had left DEBUG = True in settings.py.  Django docs really emphasize that leaving DEBUG=True when the site is in production is bad.  The site is inaccessible by anyone not on the local network, and is only even looked at by ~5 people regularly.  Aside from security reasons, is there any other downside to operating permanently in DEBUG mode?
