Objectively, there is no argument against print text being superior to hand written in every way from legibility, density and universality. If one only happened to have a real hand drawn diagram, you can of course excuse any lack of readability, but to go out of your way and intentionally degrade digital content to the level of hand drawn should be inexcusable. This is purely style over substance and that should have no place in technical content.

I’ve used Excalidraw and downloaded an external library with the k8s icons.
Also played around with non-default colors to help with info hierarchy.
Hope that helps!
