Isn't this, in a very roundabout way, an echo of docker? Or at least the abstraction Docker relies on?

I definitely see this as an alternative route from docker containers / WASM.

Yes, containers and unikernels are possible answers to the same issue. If you consider an application running on a virtualised OS you have three layers: hypervisor, os, application with some duplication of functionality between the hypervisor and the os.
From there, if you want to simplify you can either add hypervisor-like isolation functionalities to the OS (containers) or move the little that’s actually needed from the OS into the application (unikernels).
That’s why Docker bought MirageOS a few years ago.
