No, it should go under "planner improvement". If this were a bug fix,
it'd be a candidate for back-patch, which IMO it's not --- if only
because of the risk of plan destabilization. But for a more direct
analogy, if you'd submitted some other improvement in selectivity
or cost estimation, that was not a bug fix in the sense of "corrects
outright wrong answers", would you expect it to escape feature freeze
at this point?
Beta or no beta, there has to be a pretty good argument why changes
should go into v11 and not v12 once we're past feature freeze.
