Yes, thats the main reason, hence no openrc on manjaro any longer.
We plan to implement runit and s6 as optional init, but openrc remains default.
Technically, all non systemd stuff shares packages without the nasty systemd octopus.
As reference, out of 200 packages in system(core) repo, 60 packages are effected by systemd, and we happily eliminated this.
Generally, artix is not manjaro, will not hand holding the user, will not have dozens of iso out, will not target newbies.
Nope, you could easily add manjaro extra and community repos instead of arch community and extra.
But we do not use manjaro by default, since manjaro packages come in vast majority directly from arch.
Our concept is different, we do not take binary arch packages, we build them ourselves by importing PKGBUILDs that can be taken from arch because they don’t have systemd tied to them.
