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.

I don’t understand how this is any improvement over pkexec

That has the same problem as sudo: the SUID bit is set for it.

The fact that run0 uses polkit is more of a byproduct that this kinda authentication is already done with polkit all over the place in systemd. You can have individual subcommand accessible to different users (for example everyone can systemctl status, but systemctl reboot needs to be in the wheel group) which is why its generally used within systemd already. And it wouldn't surprise me if again you can do it with this as well, limiting what commands can unconditionally run, need prompt or are completely blocked.
