It’s remarkable that Apple doesn’t have a first party solution to this yet. They used be, or aspire to be, at the forefront of OS research.“The most advanced Unix”.
UNIX was already winning the server room and workstation market before Apple, that is why they came up with A/UX in first place.
The Hollywood studios that now use Apple, would be using SGI previously.
On iDevices, UNIX APIs aren't even that relevant for app development, even basic stuff like networking has been superceeded by Objective-C specific APIs.
So no, I don't see anything UNIX related where Apple has helped to caught on.
Moving beyond UNIX, now that is a thing NeXT and Apple have done a lot.
“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.
I’m sure they did, it’s even stated in the first paragraph I quoted: “But first, let's clear a few things up: is this kind of logic new? No, it certainly is not.”
It’s just that influence is not all about being first.
They’re not even trying, now.
