well - we waited and got other features in the past and we will wait and
get new features in the future too...

well the planner has improved dramatically in the last years - we have
apps here that are magnitudes faster with 8.1(even faster with 8.2) then
they were with 7.3/7.4 - most of that is pure plain planner improvements.
And I don't really believe that adding proper per statement hint support
is any easier then continuing to improve the planner or working on (imho
much more useful) improvements to the statistics infrastructure or
functionality to tweak the statistics usage of the planner.
The later however would prove to be much more useful for most of the
current "issues" and have benefits for most of the userbase.
