Apt/dpkg is flexible enough to allow the removal of any extra created files at package removal time if the package maintainer wishes it. Apt has a purge command that will remove the package and all its config files. The package maintainer can then write a post removal script that checks to see if the purge command was given, and if so, remove whatever other files that the package created.
