Why isn't there any hype on multikernel?

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Interesting! I had not even realized that this was a problem, though it makes sense now after your description. How realistically feasible is this type of approach, though, given that the manufactures can always just ignore the kernel's request to reprogram them and continue to access the bus and memory directly?
The system is complex plus a lot of legacy history. APTs for example (Advanced Persistent Threats). I think I have heard, that you can no longer guarantee that wiping the system and reinstalling the OS will eliminate them in all cases. They could for example burrow into the Firmware and Microcode.
Or look at Windows, MS has had huge problem with old drivers and other stuff they run at very high permission levels. Windows is full of stuff from 25 years ago when security did not matter.
Highly unrealistic without significantly redesigning the entire architecture, meaning all your existing equipment will not be compatible.
