Google announced smart updates and then enabled it (they had already been using this for Nexus system updates). There is absolutely nothing any developer or user has to do, so there is no documentation on it because none is needed. If you actually monitor the connection during a smart/delta update, while the UI shows the full size of the APK it actually downloads 1/4 or less of that.
It is absolutely enabled. It is absolutely working. There is no conspiracy about this. It is one of the reasons most updates take hours to propagate.
You complained about managing thin binaries, so I don't see how the developer managing that would improve anything, not to mention that it adds difficulties to cryptographic signing and verification.
