The idea is impractical, not pointless. A hybrid kernel gives most of the
advantages of a microkernel to its developers, and avoids the need for
lots of context switches. It doesn't let you easily replace low-level OS
components, but not many people actually want that.

Actually, I think there are a whole lot of people who can't afford
non-stop server hardware but would greatly appreciate not having to
waste time with a shutdown/reboot every time some OS component gets
updated.

YMMV.

Windows NT and Apple's XNU, used in all their operating systems, are both
hybrid kernels, so the idea is somewhat practical.
