To be clear I was trying to say I think you are are underestimating
how much work this is and how long it will take. Including all the
preconditon C reworks has to be included when considering how much
work is involved.
Why can't we just go forward with what Zhi already drafted? Do we
really need another side quest?
I cannot forsee rust bindings for vfio until sometime in 2027.
