It does and that's great, but it's not the root from which the system is constructed.
FreeBSD is a clone of UNIX, and all it takes is a single kernel bug for the system to break down as a whole. Yet, considering the kernel's size, it's not hard to extrapolate that there is far more than one bug.
This is not a very good architecture. In 2023, it is very far from the state of the art, and absolutely cannot be called modern.
That's probably why NeXTSTEP and Mac OS X were partly based on a mix of BSD and the Mach microkernel. Not sure of how much of that is still in current incarnations.
