This is one of the things I think Elixir is really smart in handling. I'm not very experienced in it, but it seems to me that having your processes designed around tiny VM processes that are meant to panic, quit and get respawned eliminates the need to have to intentionally create graceful shutdown routines, because this is already embedded in the application architecture.
In the same way that GC eliminates the need for manual memory management.
Sometimes it's not enough and you have to 'do it by hand', but generally if you're working in a system that has GC, freeing memory is not something that you think of often.
The BEAM is designed for building distributed, fault tolerant systems in the sense that these type of concerns are first class objects, as compared to having them as external libraries (eg. Kafka) or completely outside of the system (eg. Kubernetes).
The three points the author lists in the beginning of the article are already built in and their behavior are described rather than implemented, which is what I think OP meant with not having to 'intentionally create graceful shutdown routines'.
