In general in many corporate environments requiring kernel reboots or kernel rebuilds limits the real-world usability of any kernel feature we offer down to "non-existent". Saying "build your own kernel or reboot" is excluding a large subset of our real-world users.
Build and boot options are fine for developers and testing. Otherwise _everything_ not readily accessible when your distro kernel has booted up is essentially behind a usability (and corporate policy) wall so steep that it's essentially non-existent to many users.
So either we make this properly sysctl (and/or prctl) controllable, or just don't do it at all.
Thanks,
Ingo
