Engineers will focus on professionalism of the end product, even if they used AI to generate most of the product.
And I'm not going by "title", but by mindset. Most of my fellow engineers are not - they are just programmers - as in, they don't care about the non-coding part of the job at all.
Are you genuinely confident in a framework project that lands 19kloc generated PRs in one go? I’d worry about hidden security footguns if nothing else and a lot of people use this for their apps. Thankfully I don't use it, but if I did I'd find this really troubling.
It also has security implications - if this is normalised in node.js it would be very easy to slip in deniable exploits into large prs. It is IMO almost impossible to properly review a PR that big for security and correctness.
