You are viewing the list from a position of great privilege, due to your greater knowledge. Many devs don’t understand how sudo or setuid binaries even work, some may not even know that sudo itself is a setuid binary. Asking interview questions like “how does sudo work” yields interesting results ranging from “magic/witchcraft” to “it’s part of the Linux kernel”, even in some very senior engineers. As an educational/training tool, including at least one example of the unintended consequences of ill-formed sudo configurations and setuid binaries in GTFOBins makes sense to me.

Heck, IMO, we shouldn’t have a single role with all the privileges, opting instead for a capabilities-like system with specific admin roles for different domains of control. There are other *nixes where this was the case historically.
