Since this is a new performance improvement and not a regression or fix in any way, I don't think this will get back-ported to previous releases. Every change has the potential for breaking things, and the aim of the point releases is to remove as many bugs as possible. New features should only be added in major releases unless there is a really compelling reason otherwise.
