Perhaps if you read “Rethinking PID 1”, from Lennart Poettering in 2010, who originally wrote systemd along with Kay Sievers

“But first, let's clear a few things up: is this kind of logic new? No, it certainly is not. The most prominent system that works like this is Apple's launchd system: on MacOS the listening of the sockets is pulled out of all daemons and done by launchd. The services themselves hence can all start up in parallel and dependencies need not to be configured for them. And that is actually a really ingenious design, and the primary reason why MacOS manages to provide the fantastic boot-up times it provides. I can highly recommend this video where the launchd folks explain what they are doing. Unfortunately this idea never really took on outside of the Apple camp.”

Other than that, your answer has nothing to do with what I wrote.
