Instead of an Index Tuning Wizard, instrumentation that would
allow the collection of SQL statements, frequencies, IO counts
and CPU usage.
The data collected from such collections could then be analysed
and used as the DBA balances the number of indexes versus number
of inserts/updates/deletes, and the time of day when the query
occurs.
Yes, such instrumentation would be needed for the Tuning Wizard
itself, but a human can usually spot nuances better than a program
can.
