Well, to be fair, these user space components are often judged as catastrophes from the point of view of Linux/UNIX users/admins. In other words, Windows components for same tasks were never scrutinized at this level. Windows users used often scoff at me when I am troubleshooting problems with my Linux boxes. But the fact is, I can troubleshoot and in most cases fix problems with systemd/NetworkManager, whereas when corresponding problems arise on Windows boxes there's really not much you can lean on, because inner workings of these components are not public, so 95% of Google searches result in total crap, and the remaining 5% reveal that design of these components isn't at all that perfect. (NetworkManager equivalent in Windows is big pile of steaming crap.)

So yeah, I don't like design of systemd. But hell, compared to dealing with Windows, it's precious.
