This is so very wrong! Logic: number of extents of an object has no impact on performance, therefore no need to control its maximum size.
Hellloooooooooo??????
Can anyone NOT spot the completely wrong logical inference?

I'd dare say at a minimum, that MAXEXTENTS was never a performance control parameter. It was in fact a capacity management one. Therefore, it shouldn't have been removed as part of a performance control exercise?
Anyways, it might make its way back as a quota control system managed by another DBMS_**** package?
BTW, another gripe: replacing the complexity of storage management parameters by the complexity of multiple DBMS_**** packages is not my idea of simplifying DBA tasks. The number of these packages in the last few versions has grown exponentially. Not good.
But then again, what do I know about "DBAing"? I'm not even certified...
