Yes k8s does not provide a out-of-box logging collection solution but since everything is in containers, we can piggyback on Docker or Containerd via deamonset to get all the logs.

Nomad on the other hand support various payload(native exec, exec via chroot, containers, even Firecracker VM by community support), so doing logging collection by end users is trickier. It worth noting that Nomad UI(a official web admin panel) has log tailing utility built-in so maybe partial work has already been done. The developers may have other concerns.
