You are trying to de-jargon topics, and that’s fine, but the two following categories do not help, they are localized habits and don’t have any value to non-english or nontechnical people, or both:

• shortenings: a11y for accessibility is not a common contraction, it’s not helpful for anyone to understand the term itself
• names of services: CF for cloudflare is not something worth defining. Names change, and you wouldn’t see this in a professional document. It’s like defining “lol”, the acronym is shorthand in typed communication, not technical jargon.

Side note, DNS stands for domain name system, it has never meant domain name service.
