Simplify REVOKE by REVOKE ALL PRIVILEGES and RETAIN OBJECTS

1) REVOKE of old grants is complex due to many things that might not be revokable in the same revoke - if one fails the entire statement fails.  Usually privileges are revoked due to a person leaving or moving into different a different role .

REVOKE ALL PRIVILEGES FROM <user> BY ALL

would simplify this into a single statement.

2) RETAIN OBJECTS

Why are objects dropped, packages invalidated or the REVOKE rejected because of the RESTRICT restrictios?  Because pre-DB2 9 there was no way of removing the implicit usage privileges of the owner of the object.  But with DB2 9 we got roles and, with them, OWNERTYPE.  OWNERTYPE allowed Db2 to identify that MARY did not have the privileges of the role MARY, and that users with role MARY did not have MARY's privileges.

So why not extend that - to identify that the id in OWNER / CREATOR has lost their actual ownership?  Setting OWNERTYPE to, say, 1 identifies that the id in OWNER used to have ownership but no longer has it; and similarly 2 identifies that the role no longer has ownership.
 

Putting these two together means
REVOKE ALL PRIVILEGES FROM <id> BY ALL RETAIN OBJECTS NOT INCLUDING DEPENDENT PRIVILEGES

would remove the ability of "id" to do any non-PUBLIC action but leave everything they did in place.  This would satisfy auditors who do not like unnecessary privileges without the overheads of recreating objects that the user had previously created.
