That‘s the problem of unikernels. There are papers how great they are but almost nobody is using them. If applications could easily get a 25% boost without much work they would do it.
But nobody is using it. So I am not trusting the „benefits“.
There are a ton of well known techniques in computer science that will make software faster, more reliable or better in other ways, that people don't use, yet really work.
I mean, if I had an easy-enough way to use them, I absolutely would.
Docker isn’t ideal, but it’s common, and the UX is decent enough. If a unikernel solution existed with near-enough quality of UX and deployment, I’d 100% switch.

The development community at large often chooses to use/not-use things (packaging solutions, tooling, engineering approaches, software architectures, etc) for a huge variety of reasons, not all of them based in any kind of logic or benefit. I suspect microkernels could become a viable solution for some things, they just need a “docker moment”.
