From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Looking at the implementation, it doesn't really implement sudoers or tools like sudoedit in any way.
systemd-run
has already been an existing tool for quite some time and this is really just a different CLI for it. That tool asks systemd to make a temporary new service and immediately run it. That, in turn, requires blanket yes/no approval fororg.freedesktop.systemd1.manage-units
via polkit.So with run0, you can either do everything or you can do nothing. In-betweens are just not a thing at the moment. There's very little new backend code running as root.
run0 bash
should behave very similar to something likesystemd-run --uid=0 --gid=0 --wait --same-dir --send-sighup --pty --pipe --collect bash
and the majority of those options have been available for quite a while.
