In my opinion, there's only little use in splitting roads at intersections only to indicate that a short part of a highway=* way is part of the carriageway of another road. However, this is a bit different with ending sidewalks or steps that run parallel to the road: tagging the connection with the road highway=footway + footway=sidewalk or highway=steps would pretend that there were an abrupt change of the direction of the sidewalk or steps by 90°, which is a bad representation of the actual geometry (example [1]). Besides, continuing steps up to the highway=* way would distort the steps, which is especially problematical with short steps and a wide road. For example, continuing highway=steps of 4 steps with a length of 35 cm each to the centre of the road that is 8.4 m away from the last step would let you assume that one step is 2.45 m long (example [2]).
