I wouldn't rule it out completely, but not in the first implementation
because
- its more work
- its not in the SQL Standard
- neither Oracle nor DB2 support it either, so its only going to provide
incompatibility
- there are some wrinkles with MERGE that means I don't want to
over-complicate it because it looks to me like it will change in future
versions of the standard
- not sure what the use case for that will be
