You make an assumption here which leds you jump to a wrong conclusion.
The K mount to Micro-ThourThirds adapter would contain all electronics and contacts required. Because the specification allows for very advanced adapters, not just restrained, tiny optical adapters. All Pentax body controls (even an AF screwdrive, if wanted) go into the adapter.
