Docker is not the last word in Linux containers. Generalising from the limitations of Docker to all container implementations is unfair (compare Garden, for example); and the Docker team are slowly coming around to heed the voices of their critics. Unikernels mostly still require per-stack implementation. That's a lot of engineering effort right now. There are halfway-houses like OSv (mentioned in the slides), but they weaken the case. I'm still bullish on Unikernels. With some work Garden's API could be adapted to run unikernel binaries. That means the ecosystem for Cloud Foundry would work almost "out of the box", as it already does for Garden droplets, Docker containers and .NET applications.
