Maybe there would be less confusion if they changed the name to something not including systemd, and decoupled the development and distribution of these clearly unrelated projects.

Then this DNS resolver could get the distribution and usage it deserves based on its own merits.

Of course, that's not going to happen, because the creators want systemd to be an OS by itself, with every buggy unreliable component standing as a monument to them only, and that means strong-arming in projects that could never compete with the existing working solutions on merits.

And maintained within the same tree so that they can change interface details between the "independent" parts at a whim.

In contrast i can pass data between GNU core utils, BSD equivalent, busybox, toybox, and expect things to work. Because the way they communicate is documented and stable.
