CAA is a term of art for a standard encoded in DNS. It stands for "Certification Authority Authorization", but most people who know what a CAA record is probably do not recognize it written as words. (I know I would need to read it several times to know that's what they meant, and I do this for a living.)

Expanding other DNS record names isn't very helpful either. I know what a Canonical Name for something is, but CNAME seems clearer, Mail Exchanger definitely isn't a helpful way to think about what MX records are for...

PTR and TXT aren't initials they're just short for "pointer" and "text" neither of which is much help divining what they're actually used for, and presumably AAAA doesn't actually stand for anything at all (?) other than it's four times bigger than the A record.

4 A's for ipv6 of course, and 1 A for ipv4. How could that possibly be confusing?

Had I been given a vote we would be using AAAA and AAAAAA records.
