It may be worthless to aggregators but a powerful attribute for applications that are built atop APP. Imagines a CMS that uses APP to perform its operations, the scheme could denote different meaning within the context of the CMS. You could also imagine an automated service that "converses" with an APP service. This automation could give a specific meaning to the scheme attribute again. APP goes way beyond the aggregators-space. - Sylvain
