Yes, I think this is a very good point.
For most people, you learn how to write a CV towards the end of your education and then you never really re-evaluate the whole process again; when you update your CV, you base it on what you personally know a CV to be.
Exactly this.
Part of this may be that when applying for jobs as a school leaver you don't have any work experience to speak of to put on a CV so the "hobbies" section is there purely to flesh it out and give it some content, but I remember clearly once my experience started to build wondering how on earth I was meant to keep everything to two pages and also still include all the sections I had been taught to include; I didn't know I was allowed to leave it off to make room for more relevant content.
When I learned to do a CV in the mid 80s, we were taught to include the following, in this order:
Personal details (name, address, telephone number, date of birth, marital status)
Work experience in reverse date order: where you worked and your duties (not listing achievements as is done these days!)
Exam results (including all subjects and grades)
Hobbies and interests
The names and contact details of two referees
Things have changed since then, but there are undoubtedly people of my age still using this format and not knowing it's "wrong", and if you don't know you're doing it wrong, you don't research how to do it correctly.
