I think the system still need to be able to rebuild the zonelists at run-time in response to memory hotplug [someday, maybe?]. And for now, the sysctl is very useful for testing. And, it does avoid a reboot--quite expensive, timewise, on large platforms--should one find that the default order is not appropriate.
