This is perhaps true for shrink-wrapped software (in so far as that still exists), but for B2B SaaS products, the ability to easily maintain and enhance the codebase is vital to the long-term success of the product.
Maybe it won't actually matter, because if AI generates a 5MM line ball-of-mud, it will be able to easily add features later due to the code being styled in alignment with its training, or maybe the context size limitations will allow future systems to digest the entire thing. It could end up being like coding in a very high-level language: who cares what crazy bytecode is kicked out as long as it performs within expectations.
