So if there was enough demand, this is a viable pathway to having unikernel software managed by a fully mature cloud platform. Personally I think that the OSv/Java unikernel stuff is probably in the sweet spot of industrial demand and plausibility, since programmers on the JVM are accustomed to operating at a fair distance from the OS's APIs.
Disclaimer: I work for Pivotal, we donate the majority of engineering to Cloud Foundry.
We're currently using unikernels with our Java micro-services for supply chain/logistics tracking and analytics, and loving it.

I worked on something that ended up vaguely similar, but apart of a couple of cool demos there didn't seem to be any point to it.
