It's not a legacy request type.

Alexey Zaytev documented it in 2012:

https://lists.linuxfoundation.org/pipermail/virtualization/2012-December/022313.html

It was in the VIRTIO <1.0 spec:

https://github.com/rustyrussell/virtio-spec/blob/master/virtio-spec.lyx

I don't understand why it wasn't part of VIRTIO 1.0... :/

It's worth sending a patch to add the request type to the spec again.
