agents are becoming the de facto standard interface for everything, whether you like it or not, so it depends on the intent you have for a project, or "product" as OP phrased it, which has a more contextual implication that the intent is to get others to buy it
ironically, I did sell a kirby many many years ago
the idea is likely way more about business purchases and SaaS than consumer products, though I did have an agent do deep research to give me options when deciding on a new mattress
