This protects other users from unruly processes within the same kernel. How will this behave in a cloud/hypervisor environment? If Linux is the bare metal kernel, will it protect others from an unruly VM of another customer, for example. This behaviour has existed for years, I've been surprised how it's been able to remain so low-key.
