Gee, um, isn't the kernel a shared library? At least the syscall part.

No way! Remember that the PC was a step backward in computing;
everything that PC designers had to contend with had already been
done years ago.
DEC's RSX-11D and IAS (later merged) both featured loadable
device drivers. They were actually run as tasks, and a magic
system call installed them into the moral equivalent of [bc]devsw
and attached their interrupt vectors.
RSX also featured shared librarys too.
