I'm not sure, but perhaps the area:highway-proposal [1] is useful here.
There are already numerous highway areas for things like market places and piazzas, but it's done as highway=x;area=yes, not with its own key. These are properly rendered on Mapnik (e.g. http://www.openstreetmap.org/browse/way/27918828 ).
(I don't see any need to change this unless we adopt a proper area primitive).
Before we have to discuss the general pros and cons of that proposal: I don't think it's necessary to tag all streets with an area (but it would be possible, sure), and I don't think, it's useful to do so in general before we have tools to support that. But I think, in cases where the line generalization of a highway is not enough - like it's here in the steps issue, it would be useful to do that.
As I said, yes, an area for what is a significant area rather than a linear feature is the obvious method, but the difficulty with steps is indicating which side(s) are the top and bottom. (We also have L shaped step areas, and semi-circular ones among others I have come across in the last week).
The additional highway:steps would stay at separate ways "on top" of the area.
This shouldn't be necessary, any more than any other highway area. It's like putting a node for parking in the middle of a parking area.
