That's Poettering for you. His lack of self-awareness is legendary.
This is why I use Devuan.
When Poettering wrote code for Avahi, I didn't notice any problems, because absolutely nothing relies on the protocol Avahi implements, for any purpose whatsoever, so if it doesn't work, the situation is exactly the same as it would be if Avahi worked perfectly. There's no way to notice the difference, without actually attempting to use wireless zeroconf for something, which as far as I am aware not one person in the entire history of computing has ever tried to do. So if he'd stuck to working on that, we wouldn't have a problem.
But after the pulseaudio debacle (in which Poettering's software screwed up the sound my system so badly, I wasn't able to get it working again even after completely uninstalling the package that caused the problem and reverting to my former configuation, and so I ended up reinstalling the entire operating system distribution from scratch), I swore off ever installing any software written by Poettering on any computer ever again. And then somebody decided to let him rewrite the init daemon, which is *kind* of important. Nope. Hard pass. That is NOT going to be a thing on any of my computers, or any of my employer's computers, or any other computer that I ever have to touch.
