Much software, when you open it, perhaps GDB if I remember the debugger, there is only one small main() function calling the rest of the system, startup, etc. Similarly, I think of keeping init.lua clean for my Neovim Lazy plugin. After all, its name doesn't bear any of our conceptual connotation and we are in the domain of lazy concept, we need to exit that domain and get to our own, so keep init minimal.
