read a blog article about #systemd that talked about how it ultimately makes a lot of things possible for sysadmins that were simply not possible or too hard to accomplish on other init systems, and i think this is just another classic example of the pareto principle ("80% of the users use 20% of the product's features -- BUT that 20% is not the same for all of them")
to all the individuals, the fact that systemd does all those seemingly unnecessary things is annoying and they'd probably feel okay replicating one or two features it lacks using other means, but if you scale that up collectively, you'll end up with people whose systems are configured very differently, because they have different needs and requirements
so people whose job it is to actually support these set-ups (like redhat or distro maintainers) would much rather everyone use a single piece of software that does "too much" than have to solve a new mystery every single time
i currently run #alpinelinux, which does not use systemd, and i'm fine with it, but this is a distro that's targeted to a specific set of users, i wouldn't advise a typical gamer or creator to install it
and i think that should still remain an option, i like openrc
and feel it does the things i specifically need well, and it's sad that some software now wants to specifically depend on systemd components
in an ideal world, instead of developers just announcing "$software
now requires $systemd_component
to work", we would have a period of discussion where the devs would ask "we need this functionality to be available to our software, please come up with an API that would allow this to happen, then write software that would make it work", and instead of a hard dependency on a single component, you would have different programs that people can pick and choose, and one of them would still probably be a systemd component
but this doesn't work in a "bazaar" model of development, where frequent releases are expected, and depending on what that functionality is needed for, you can't delay a security or accessibility improvement by a year or two!
