On server hardware, I perform boots infrequently, and really, really, really want them to work right.
My philosophy is different. Make a change to a server, reboot.
The goal is to eliminate surprises if the server is restarted unexpectedly. I'd rather have them during the maintenance window than at 03:30 after a power outage.
Anyway - to systemd.
I was appalled when we moved up to Solaris 10 and the SMF facility started to replace init scripts. It felt wrong.
I adapted. It's not wrong, it's just different. Better in some respects: you can still use bash scripts, but you have better control over them, a standardized way of managing things.
Now we're abandoning Solaris for Linux and ... I'm appalled that 'linux' default method is still .. init scripts. And a hodge-podge of stuff like djb, systemd, etc, all with competing fan boys and advocates.
I'm a big fan of knowing my systems will initialize properly as well.
AT&T ran into a little restart issue, as I recall, in 1990 when a software upgrade gone wrong crashed much of the phone network. Among the problems were that most of the switches had been upgraded in place, many over decades, and there had never been a cold-boot restart. There was some uncertainty as to whether the system would start up properly or not.
While long uptimes are nice, I generally prefer seeing a few reboots annually just to be sure things will come up right. There's a balance between "restart for every change" and "restart regularly enough to not be surprised at 3am".
