Clear! The thing is that you quoted a topic in which "Fundamentals" was the name of the course, and then you used it in a different way without specifying it... it was an easy misunderstanding
Just to be exhaustive, all the things that you mentioned are just a fraction of GUE Fundies; and they are not even the more important.
To give an idea, when I first tried for a tec-pass, I didn't get it essentially for a lack of team awareness. There is an entire part about standardization, that you may like or not, which is strongly related to the team approach to diving of GUE.
Saying that GUE Fundies teaches only basic skills is very reductive, at the best...
Obviously, GUE is not the only agency teaching these things (at least UTD and ISE have the same approach), and I am sure you can find many instructors across other agencies able to teach the same things.
Regarding the skills, I believe you that they existed and they were being taught way before GUE was even born.
