Needs to? Is there some new law mandating all landing pages must contain exclusively handwritten text that people haven’t heard of?

To your actual point, the people that would take the landing page being written by an LLM negatively tend to be able to evaluate the project on its true merits, while another substantial portion of the demographic for this tool would actually take that (unfortunately, imo) as a positive signal.

Lastly, given the care taken for the docs, it’s pretty likely that any real issues with the language have been caught and changed.
