It's useful for anyone who wants to use it for testing purposes.
And it's useful to make sure the qemu/kernel/kvm machine check
injection code works.

RAS features generally need associated testing/injection hooks,

qemu has support for triggering MCEs on the monitor.
Also the KVM code base has support for forwarding the MCEs automatically.
