The seL4 and QNX users would probably disagree with you. Strongly.

Microkernels offer excellent security and isolation benefits that
monolithic kernels cannot provide.

It really is a pity Linux didn't go down the microkernel route. I suspect
many of the kernel-level vulnerabilities would be far less severe in such
an environment.

In case you are unaware BTW, the monolithic versus microkernel design was
a _major_ debating point in the early days of Linux.
