You're right, it is mostly neophobia. I sort of tried to say that in my top comment; I don't think that systemd is technically inferior, I just can't yet justify switching to it.
But, I've been meaning to write about this for a while: I think neophobia is starting to become an unnecessarily religious article of faith in the technical community. I run a small consulting shop, we support (or try to support) just about everything under the sun. What this means is that every single time there's a significant hardware change, my hardware guy has to be on top of it; every time there's a new mobile device UI change, or platform, or service or software, he has to get to know it right away; every time PHP or MySQL or Linode or any of a number of aspects of Linux changes, I have to be on top it; every time a new operating system version is released, we have to be familiar with it.
And every single one of those little ecosystems assumes that you have the time to sit down and read and digest their documentation or play with their new way of doing things. And, if you don't, or if you miss something, you're chastised by the community (or, worse, by your customers).
It is exactly like being in college and having every one of your professors assign 3 hours' work each night and then wonder why you're making a big deal of it.
To make things worse, when something goes wrong, you know as well as I do that you rely heavily on familiarity. You don't want to be looking things up in a man page trying to remember the specific incantation for a particular thing while your budget shrinks by the second. I was lucky that the smbd/nmbd fault happened on my personal system; if it had happened to one of our clients, who has everyone using a centralized smbd share, then smbd failing to start would have stopped work for the entire company.
So, yes, it's true that I am not a fan of change for change's sake. Lennart argues that that's not what's happening with systemd. Maybe he's right. But, it is still another massive change in something that I use and support on a daily basis, that is going to irretrievably consume a little bit more time out of my limited life, that is going to force me to throw out all of the old familiar tactics ("hmm ... new client, their MySQL isn't starting, dunno where MySQL logs are on this system, let's start with `grep -R mysql /var/log/∗` ... oh wait, this is a systemd system, that doesn't work").
From that standpoint, I feel like the technical justifications in favor of systemd are a bit on the weak side.
Systemd is actually way better at logging why a service did not start. With sysvinit I often had to figure out the exact command the shell script would start the daemon with to see the stderr output. Systemd just logs this by itself and you can see this output in e.g. systemctl. This saves loads of time.
