This is a case where the abstractions of the C programming language start to break down. 0 is indeed a null pointer constant in C, but the hardware sees 0 as a memory address like any other. Some systems have nothing valid there, but some other systems (like this one) put exception vectors at this location. When certain types of hardware interrupts or exceptions happen, the CPU jumps to certain fixed addresses around address 0 (the specific types of exceptions and the specific addresses are a property of the CPU architecture).
The second approach offers broader feature support, seen in projects like Cloud Hypervisor or QEMU microvm. Built for heavier and more dynamic workloads, it supports hot-plugging memory and CPUs, which is useful for dynamic build runners that need to scale up during compilation. It also supports GPU passthrough, which is essential for AI workloads, while still maintaining the fast boot times of a microVM.

This downloads the package from a JS CDN and adds it to your vendor directory and updates your config/importmap.rb. The package then gets automatically included in your application with the javascript_importmap_tags ERB tag included in the of the default HTML templates. You can see how this gets expanded if you look at the source of any generated page in your browser:
