You've almost reinvented one of the points that was made in the last
go-round on the subject of hints, which is that keeping them out of the
application code is an important factor in making them manageable by a
DBA. Hints stored in a system catalog (and probably having the form of
"make this statistical assumption" rather than specifically "use that
plan") would avoid many of the negatives.
