This is my experience as well. Suddenly logins take 30s. Why? Some new systemd problem with reverse DNS. Suddenly reboots don't happen. Why? Systemd is spinning on a task that didn't used to spin. Yes, probably fixable, but not discovered until trying to reboot. Can't login at coffee shop WiFi suddenly. Why? Some random systemd DNS issue. Is my system more secure? Maybe, but possibly because it breaks so often that low uptime keeps it safe! For my servers, I seriously have to cross my fingers and have the colo phone number handy whenever I reboot, fearful that they won't restart because of some random systemd interaction that happened on some previous upgrade. It's gotten that bad.
