In addition to the author being a long term contributor, the piece seems to have been a leader for a discussion[1] on the qemu-devel mailing list (where it seems to have been positively received).

Much of this is written in the context of the new vfio-user proposal he linked at the end. This is a new, more flexible mechanism for implementing device emulation in a separate process. That emulation code can certainly be written in rust, providing a gradual path toward conversion.

As background, vfio-user was at least partially born of some discussions and a proof of concept last summer for using SPDK to provide virtual NVMe devices into QEMU. These are intended to be high performance devices.

Except SPDK is written in C. So maybe the title should be rewrite SPDK in Rust!
