OK, it is not dead-end for everyone, because the highway=pedestrian area 
(plaza) 35826685 is connected to the driveway. We may route pedestrians 
on the edges of the highway=pedestrian area. We might route bicycles too 
(AFAIU, it is allowed in Finland with maxspeed=20, but not allowed in 
Germany).

It is the same thing if you had a oneway highway=service that ends in a 
path or steps. It is not dead-end for pedestrians, but would be a 
dead-end for cars.

I wrote some months ago about a possible project to highlight dead-ends 
on the map, but nobody replied. I think it should be a set of 'dead-end 
layers', one for each mode of routing. Then you could easily survey all 
those nearby suspectable cases when going for a walk or a bicycle trip.

Pedestrians can use steps, cannot legally use highway=cycleway. For 
bicycles it is vice versa. Both can use paths and most ways except 
motorways. Cars can use all ways except those meant for bicycles and 
pedestrians. There are really multiple routing graphs to consider if you 
want to check for dead-ends properly.
