Why Oracle does not allow rollback of DDL statements?

I have always been surprised why Oracle does a implicit commit when DDL statements (e.g create table …) are executed. DDL statements simply write information (insert, delete and update) to data dictionary, so why DDL statement cannot be rolled back. Am I missing some thing?

I was learning SQL Server few months ago and I noticed that SQL Server does allow rollback of DDL statements if I am not mistaken. It lloks like there is something in Oracle architecture which prevents rollback of DDL satements. Rollback of all staements should be allowed not just of DML statements.
