Yes? If I've developed a prompting style over the past four years that produces efficient and secure code bases with novel features, I consistently out-perform my colleagues using the same tools, and it is how I make money, then I don't see how it is not a trade secret.
Talking to customers is the most important thing, not sure prompting really matters at all, LLMs lack true novel creativity and cannot prioritize product features based on direct customer value.
