I agree that the optimizer should be improved here, but it's not really
a "bug". I think what you are requesting is considered more of a feature
to make the optimizer smarter.
The optimizer will never be so good that it always picks the best path.
Consider a 100-table join: would it be a "bug" if it didn't find the
perfect join order?
