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.

This just sounds like a bad idea, a solution in search of a problem. Sure, sudo is a setuid binary, but it's a fairly simple program, and at some point, you have to trust the code. It's also a very fundamental piece of the system that you want to always work, even (especially!) when other things get borked. The brief description of run0 already has too many potential points of failure.
I mostly agree with your write-up here. That said, I do think that systemd does want to eliminate SUID. I also think they want to absorb most of the low level system plumbing.
There are other applications that use suid (like
newuidmap). And there are programs that use capabilities (likeping). I'm pretty sure that this logic will be used to justify assimilating those applications too. But I'm sure that the crowd will cheer them on as if they did something revolutionary.
