AFAIK it is not recommended to modify a container setup to allow running
systemd because of some security implications. Thus there won't be systemd
available in normal container setups.

Frankly I don't understand your answer.

Personally I think that running a DNS resolver like unbound in a Docker
container on e.g. an elastic Kubernetes cluster is something users definitely
want. Thus requiring systemd for installing and using unbound package is a real
obstacle for such a setup.

I strongly disagree.
