You definitely could, but the OP voiced a concern that granting this package could potentially be a security risk. Always a valid concern and one of the reasons why PUBLIC doesn't get granted to it like dbms_obfuscation_toolkit was. (Saves us the step of having to revoke it).

Now is it overkill to tuck it in another procedure to grant? Possibly, but not my call to make. And as of 10g, this package is included in standard edition. Though using it with ASO, TDE, etc would require more of a license than SE offers.
