The LTE Bluetooth standard actually does make large inroads towards removing a lot of the less clear parts of the standards, and reducing the size of the specification. It is still far from perfect, but attempts are being made by the industry to clean things up. WiFi Direct (which is also somewhat horrible, but somewhat less), is also a competitor in this area. It hasn't seen a lot of adoption, but there are a few things that use it. Apple's AirDrop is also a proprietary protocol that can handle a lot of this peering stuff, atop WiFi, and they seem pretty committed to keeping it around for all their stuff for the foreseeable future.
