We prefer to follow the Unix way of doing things, "do one thing and do it well."
znx, for example, doesn't attempt to do more than what it was designed to do. Our focus on AppImages also indicates that we prefer to have to manage one file (the AppImage file) instead of a multitude of packages. Nitrux itself is deployed as one file by znx. The operating systems that VMetal runs are also contained as a single file.
SystemD is more than an init system which doesn't follow that way.
@carl SysV is exceptional in that it works, but it's not the best out there. Next things are to try to implement other, newer init systems.
Generalistic and moderated instance.
