That's assuming no human would ever go near the code, and that over time it's not getting out of hand (inference time, token limits are all a thing), and that anti-patterns don't get to where the code is a logical mess which produces bugs through a webbing of specific behaviors instead of proper architecture.
However I guess that at least some of that can be mitigated by distilling out a system description and then running agents again to refactor the entire thing.

The problem with this is that the code is the spec. There are 1000 times more decisions made in the implementation details than are ever going to be recorded in a test suite or a spec.
The only way for that to work differently is if the spec is as complex as the code and at that level what’s the point.
With what you’re describing, every time you regenerate the whole thing you’re going to get different behavior, which is just madness.
You could argue that all the way down to machine code, but clearly at some point and in many cases, the abstraction in a language like Python and a heap of libraries is descriptive enough for you not to care what’s underneath.
The difference is that what those languages compile to is much much more stable than what is produced by running a spec through an LLM.
Python or a library might change the implementation of a sorting algorithm once in a few years. An LLM is likely to do it every time you regenerate the code.
It’s not just a matter of non-determinism either, but about how chaotic LLMs are. Compilers can produce different machine code with slightly different inputs, but it’s nothing compared to how wildly different LLM output is with very small differences in input. Adding a single word to your spec file can cause the final code to be unrecognizably different.
And that is the right assumption. Why would any humans need (or even want) to look at code any more? That’s like saying you want to go manually inspect the oil refinery every time you fill your car up with gas. Absurd.
Cars may be built by robots but they are maintained by human technicians. They need a reasonable layout and a service manual. I can’t fathom (yet) having an important codebase - a significant piece of a company’s IP - that is shut off to engineers for auditing and maintenance.
