while those things sucked, patterns imprinted on devs minds, passed on from generation of devs to the other until that's just the way things are done. CI is a good example, as are some of the documentation practices. Lots of teams that don't use agile or scrum formally, follow those concepts because that's just how they've seen others do things in the industry. I predict, LLM work will get some overdone and abstract thing like agile/scrum that lots of people hate, and few thing is useful, but then out of it the actually useful bits and pieces become self-organizing standards of sorts.
