That's what delegation looks like, but it needs a better process. They could be committing plan files alongside any nontrivial change to application code, and the plan file can have everything you'd care about, like the invariants it held to and why, the rejected ideas and why, the acceptable risks and why, etc. This is solved by better usage of LLMs, not less. The divide to me isn't engineering skill vs those who lost it, it's people who care vs. those who don't care. It's a higher level thing now that we're working at a higher level (delegation).
