The core is still clearly monolithic. It's very convenient to run things in userspace, and many things can be run perfectly well in userspace; I suspect the difference between reading a filesystem on CD in userspace versus kernel space is nonexistent timewise and usually unnoticable added pressure to the CPU and memory system. Like many modern systems, there's enough power to let people do things the easy, flexible way or the maximally efficient way if they need that.
