Like many new features in disk drives or other products, they're often driven by a single or small set of large, paying customers to prove them out prior to being standardized. Given time, most eventually settle on common interfaces to reduce costs. This is a continuous process, the "concept -> development -> one customer -> standard feature" path. Unfortunately, you're right, it's very difficult for individuals to interact with some of the standards committees, and the exact working details (including detection) of these features are often not made public for competitive reasons in their initial offerings. --eric
