Further thoughts on this topic.
I am convinced that the reason that MB discarded the engine oil dipstick (although it has been reinstated on most recent models after complaints from the techs*) is that the typical MB owner is not expected to physically check oil levels. All the other liquid levels that need to be checked are readily visible by opening the hood.
That's why a sophisticated oil level monitoring system was included to advise the driver at the cluster when the level has dropped enough for oil to be added. The message even advises the quantity of oil to add.
* why did the techs complain? How else can they readily check if coolant has mixed with the oil, as in a head gasket problem? It shows up instantly on a dipstick.
