Duplicated driver in a new language means nobody has a real incentive
to use it in production. That really mutes the signal we get out of the
experiment. At the same time IIUC building the Rust code is not trivial,
so IDK if we're ready to force people to use it. Ugh.

Do you have any idea how long it will take until one can 
 dnf install $rust
and have that be enough to be build a kernel (for the two major arches)?
