One major thing that we get from systemd is cgroup management, that gives resource and namespace management at a per process level. This has actually been in the kernel since 2008 but to use it you had to have some really bad ass programmers to give you an access interface to the features. It's now trivial to run a hosting server where each site has a set amount of cpu and ram without the virtualization overhead. Before that the option was openvz and before the option was virtualization. There is a very loud minority in the linux community that doesn't want things to change. There are a ton of linux users who's lives this improves, and they are not as noisy. Debian is the larges distro and when the maintainers took a vote systemd won with like a 60+% majority. Almost all other distros that are going to, have switched over the last 3 years.
