The same wording would mean the same requirements, wouldn't it? Why would you want to impose unnecessary requirements that lead to potential security risks? dlsym does not need to allow data to be invoked as a function. The pointer returned by it does not need to point to data. The only requirement that is necessary is that it can be converted to a pointer to function, resulting in a pointer that can be used to call the function.
