If you are a web programmer sure. I write embedded code, I know all the things you are talking about in the abstract, but I'm not good at them because none of them have ever been relevant for anything I do. Give me a few hours and I can figure it out (maybe minutes, maybe days? - if you know this area your guess might be better than mine), but it isn't something worth my time.

there are a lot of people who are not programmers at all. I can teach my plumber everything you said (learning it myself is the easy part), but it will take years. In the end they just know "that button I'm pointing my finger at should be yellow not red". How to we transfer that pointed finger to a ticket is the question here.

This can be a substantial effort, especially if you're not familiar with the project.
