Re: "Religion gave way to pragmatism"?
Although I have used OSX, I'm far from an expert on its inner workings.
But regarding things like plist, at least you can delete them individually. Far preferable to the registry, I'd thought?
Even if launchd is comparable to systemd (I don't know), I'd say that having some monolithic thing like that that is owned by and maintained by a large corporation like Apple, whose existence depends on it working correctly, is not comparable to having systemd in Linux. I just don't like large monolithic and hard to grasp systems in the FOSS world. They tend to ossify and eventually need to be completely replaced.
They sure don't adhere to the original Unix idea.
