We generally aren't in the habit of using "random" scripts to do anything. They're usually carefully developed to do exactly what we need them to do, precisely, and nothing more. Not the giant pile of buggy ass code and security nightmare that is systemd.

By the way, you don't seem to be aware that you can use any language you want to create startup "scripts" including compiled binaries, if you hate shell scripting so much.

Do you even know any shell script? Serious question. Many 'bash' haters know nothing about the language--starting with calling it 'bash' instead of 'shell script.' There are several different flavors just of shell scripting languages, and bash is only one.
