daemon resource control

This thread considers some aspect of systemd ie the ability to control various system resources. One specific case in the thread is network control/filtering.

This seems to be a relevant page which describes what systemd can control about a service (or group of services).

Can I do this sort of control in Artix? Do I have to learn all about cgroups?

I don't have any specific need, but security is becoming more important so these controls might be needed one day.

I don't know why Poettering et al. decided to move this sort of functionality into the init system. I feel that's sort of wrong.

What is available to do resource control for any process?  I have no idea if this just comes down to using ulimit in my run shell scripts. I don't think ulimit can prevent network access, but that might be needed. Apparently there is a tool called unshare, but I have never used it and it involves namespaces  which I don't know about.
