I see you chose to respond to my weaker argument and ignore the second: "A plugin is less secure if developed by a coding agent when compared to any possible programmer. Is that a valid assumption? Aren't all of the well-known issues in WordPress plugins the fault of programmers?"

You are also conflating professional engineering, a licensed profession requiring insurance, etc. with software "engineering". You don't want to admit that the quality of "engineering" that is available on Upwork or in the average contract software developer is likely as bad, in fact, probably worse than the latest crop of LLMs.
