thanks, it is capable to model a lot more (lanes, road surface without
explicit "inner" borders, detailed barriers with less effort, ...),
but unfortunately I'm not a programmer to prove it could work.

current renderengines of OSM won't be able to do this, because the
polygons are not closed (maybe this could be done by simple
preprocessing).

no, that will be necessary for you to model/define: you will have to
model 2 stairways: one with 12 and one with 7 steps.

this is done by alignment/positioning of the upper and lower borders.

if it gets too big, simply make several of them, like we do always,
and eventually group them with a "superrelation"
