I noticed that when creating a db with --clean, at least the language data doesn't get added into the db. Like the default accounts this data is a requirement for the server to function properly. Without this info users are not able to e.g. add a new release. By including this data separately from the actual downloadable data dumps, you will save some bandwidth again because people don't have to download the major files. Instead of making the basis required data available in trunk you could also create a smaller separate db dump on the ftp server.
