How much value are you going to be able to extract over its lifetime once your customers want to see some additional features or improvements?
How much expensive maintenance burden are you incurring once any change (human or LLM generated) is likely to introduce bugs you have no better way of identifying than shipping to your paying customers?
Maybe LLM+tooling is going to get there with producing a comprehensible and well tested system but my anectodal experience is not promising. I find that AI is great until you hit its limit on a topic and then it will merrily generate tokens in a loop suggesting the same won't-work-fix forever.
