IMHO SQL profiles are a first step in this direction. In fact with them it is
possible to store information describing mistakes the CBO does. Their main
limitation is that they are bound to a single (or few similar) SQL
statement(s). Therefore, to close the loop, they should enhance them to store
generic information about the mistakes.
