I mean.... I have 12 years experience and I do each and every one of these things in the last year. I've submitted Pull Requests with 5k lines of code. Some things are impossible to efficiently test, or force the code to be contorted to satisfy the test. I'm currently editing an ancient procedural code base which is almost older than me and one of the files is over 50k lines. When we edit it we try to add comments as literally no one on the team has any idea how anything works. If you figure it out, you are almost guaranteed to not remember it by next week.

IMHO a lot of dogmatism leaves you over the years as it just doesn't matter. If you insist on a dogmatism you are limiting yourself and your team.
