I would agree that DSN support seems like a nicer alternative to just copying dj-database-url, because it not only focuses on 12factor configuration in enviroment variables, but also enables some additional flexibility for the database connection option passing.
As for 12factor, I think https://gist.github.com/telent/9742059 is a good read as to why exposing as enviroment variables maybe not the best motivation. Having to accommodate settings, like database connection information, just so they can be fitted into single string put conveyable by enviroment variable is a case in point. We likely can do the same for Cache addresses as mentioned previously, although we may end up inventing new URI schemes do to that.., but django overall has multitude of other options that are not as easy to stringify.
