> It is a bit weird to see LLMs suddenly being presented as the reason to follow what are basically long standing best practices.

About 95% of the work needed to make LLMs happy is just general purpose better engineering. Units tests? Integration tests? CI? API documentation? Good example? All great for humans too!

I consider this largely a good thing. It would be much worse if the changes needed for Happy LLMs were completely different than what you want for Happy Humans! Even worse would be if they were mutually exclusive.

It's a win. I'll take it.
