Is this the sort of thing that will see Oracle sending a cease and desist for them feeling infringed on their copyright and IP? They must not like their vendor lock in being affected and people discovering this better, more affordable alternative.
In that case, there even exist Orafce, a project that provides a lot of compatibility to a lot of Oracle Packages. For example, a lot of date functions, UTL_FILE, DBMS_OUTPUT and a lot more are already [art of this :)
