Wiring/PCB header or connector/common data hub yes - but my point was that has to be thought out ahead, and cannot be modified afterwards in the same way touch screens can

BoM complexity and cross commonality is a challenge in manufacturing. It’s why we see all these ‘global platforms’ among automakers trying to build one unibody core subframe for all or most of their cars, adding different panels and roof assembly for an SUV or sedan respectively. Fewer parts to stock and build is a cost saving (for the manufacturer, don’t expect them to pass that saving along) - same with tactile controls.
