I agree. For me it's a modern version of that good ol "rails new" scaffolding with Ruby on Rails that got you started with a project structure. It makes sense because LLMs are particularly good at tasks that require little more knowledge than just a near perfect knowledge of the documentation of the tooling involved, and creating a well organized scaffold for a greenfield project falls squarely in that area.

For legacy systems, especially ones in which a lot of the things they do are because of requirements from external services (whether that's tech debt or just normal growing complexity in a large connected system), it's less useful.

And for tooling that moves fast and breaks things (looking at you, Databricks), it's basically worthless. People have already brought attention to the fact that it will only be as current as its training data was, and so if a bunch of terminology, features, and syntax have changed since then (ahem, Databricks), you would have to do some kind of prompt engineering with up to date docs for it to have any hope of succeeding.
