From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

runuser I do know and you're correct it's what is expected, and actually you CAN use su you just have to make sure you use the arguement that tells it not to follow a login process, but as a syaadmin myself, none of the guys I worked with, and none of the customers I had ever worked with hitting these issues had ever heard of it. But yes you can switch user without falling through the PAM stack and be fine.
As for the fork maybe they resolved that or maybe they made it better because you only have 1 child, but I can tell you I wouldn't trust systemd that way personally from my experience. And yes Type=forking also says you should have a PIDFile and that's in case there are multiple forks you can be explicit in which pid is thr parent. There are other issues you can get into like not setting ulimits or if you have 1 script that starts multiple daemons.
