This is related to my proposition, but trouble is, there is not such thing as
'well tuned database' that will suit all queries. You can tune the database to
the hardware for example (still remember that old argument on random access
and fast disks).

It seems the system could 'self-tune' itself on minor choices. I believe it
does this today for a number of things already. More significant changes
require the DBA consent and choice - but they need to be well informed of the
current usage statistics when making the choice.
