+It must be possible to detect when an SQL feature like JOIN gets emulated. This is important because you might mistakenly develop something that doesn't scale when your database grows beyond a certain size. In settings.py we could have a flag which specifies whether to throw warnings for emulated features (ENABLE_DB_EMULATION_WARNINGS?). By default, warnings should be enabled, so you never miss potential sources of problems.
