This is not new functionality:

"There’s a new tool in systemd, called “run0”. Or actually, it’s not a new tool, it’s actually the long-existing tool “systemd-run”, but when invoked under the “run0” name (via a symlink)".

systemd-run is very useful to run tasks with specific cgroups settings, or at a specific time. It asks for password whenever needed.
