I think it's actually the opposite - whenever we pushed stuff like this
outside of core it has hurt postgres substantially. Not having replication in
core was a huge mistake. Not having HA management in core is probably the
biggest current adoption hurdle for postgres.
To deal better with NUMA we need to improve memory placement and various
algorithms, in an interrelated way - that's pretty much impossible to do
outside of core.
