I think it depends on how closely you relate "Table Partitioning" and
"Constraint Exclusion".  While you can use the latter to implement the
former, I think people expect a database that supports "Table
Partitioning" to have a CREATE PARTITION command (or something
similar).

IMHO, I think Constraint Exclusion is more useful in general and once
it is in and tested future releases will have a partitioning system
based upon it.

Have a nice day,
