It's only relevant as a privilege escalation vector when you're able to execute those programs as root, but don't otherwise have root access on the server.

It's a pretty niche circumstance. Unless an admin allows users on a server to execute some of these random types of binaries as root, it's not going to be a concern. And, if it wasn't already obvious, distros are almost never configured this way OOTB

I've seen plenty of servers in companies configured to allow sudoers to run a restricted subset of binaries as root, usually without a password. Some of them were GTFObins that the admins were not aware of until I reached out to let them know. I've also seen a couple of restricted shell setups where users could only run a handful of commands. Can't recall if I checked to see if any of them were GTFObins.

I wouldn't say this is the most useful h4x0r tool ever, but I wouldn't say it's particularly niche, either. This kinda stuff is definitely relevant in older large enterprise-type Linux/Unix environments.
