I am not sure what is meant by other uses. I'm picturing a web service providing a purely procedural model of how to use it: Perform these steps and you will have bought a computer from us. "Us," let us suppose, is hardware.com, the dominant retail outlet. Suppose what the user wants is to find a computer at a bargain price, defined as "less than what hardware.com charges." Then there may be a way to use hardware.com's service and other services to accomplish this goal, but hardware.com has no motivation to broadcast it. The optimal model of their service, from a planner's standpoint, is a detailed description of IOPEs for each message you can send them, because that would allow the planner to compose those messages in arbitrary ways with each other and with messages to other web services. For such a model to be produced and kept up to date, someone must have an economic incentive to do it.
