I think you are mistaken. Obviously InfoSec is a rather generalising term, while you are abstractly describing the work of someone that works in Application Security.

I would rephrase the question... what InfoSec jobs doesn't involve spending writing documentation?

pentesting? 20% finding the low hanging fruit, 80% writing and explaining your findings.

forensics? 10% finding how they did it, 90% writing and explaining your findings.

malware/policy/security/cloud security analyst? 100% writing and explaining your findings.

the list goes on and on... you are basically and a slave for word processing software, thats why totally understand OP quitting infosec.
