eDP is quite common these days especially in laptops with elaborate hinges that have 4K screen options. LVDS requires 40 differential signaling pairs for displaying 4K resolution, eDP requires only 4 and even that can be reduces to 2 if DSC is used or your display adapter and panel support HBR3. However for LVDS and eDP the physical connectors can be drastically different but in all honesty this has very much to do with the physical design of the laptop rather than some anti consumer conspiracy. Depending on the hinge mechanism, the wiring length as well as other factors such as does the same cable need also to support power, USB (camera) and audio (microphone) connectivity you get different designs.
