It *IS* an option. You need to apply an patch to enable that option. Since
you are skilled sysadmin, you know how to do that. Most newbie-users for

patch, so no problem for them.
As to why it is not in the Linus kernel - it is not because Linus said no.
If you think you know better, you fork your kernel, call it secure-linux or
something and maintain it. As simple as that.
