I've noticed that things like "decision documents" and complete feature or service {proposals,white papers,"one pagers"} have become acceptable since the start of the AI {boom,bubble} in a way that they weren't before. It's now seen as valuable for an engineer to lock themselves in a room and write 4 pages of specs for something they're working on, since the expectation is that this will speed things up when doing the actual coding. I have personally always liked to work this way, but have had to hide it. Now, even if I'm not really leaning on the AI for implementation (and not at all for writing the {spec,vision document}), I'm seen as some kind of LLM whisperer, even if I'm more on the Luddite side.

In engineering of all kinds (or at least the ones I'm familiar with), nothing really beats calmly sitting with your thoughts, stating a problem, then getting up and walking around while you think about it, then sitting back down to write down a possible solution, and then asking colleagues to read it.
