If a class only overrides __getattr__, then I agree it should only add to __dir__ (most likely by using a super call as Georg suggests). If it overrides __getattribute__, however, then it can actually deliberately block access to attributes that would otherwise be accessible, so it may make sense for it to alter the basic result of dir() instead of just adding more attributes to the end.
