Interesting work.

I feel that with the uptake in container technology, kubernetes, serverless approaches, with managed runtimes, running directly on top of type 1 hypervisors, the have kind of achieved unikernel ideas, even if not in an ideal form.

The usual worse is better outcome.

Naturally this doesn't fit the traditional C and C++ execution model, due to the expectations of a POSIX environment instead of the rich runtimes from managed languages, which is where I see the value of this kind of work.
