Hi Mateusz, Hi Candid,
steps=* is used worldwide on 8455 objects in osm (according https://taginfo.openstreetmap.org/keys/steps) and http://wiki.openstreetmap.org/wiki/Key:steps is redirected to http://wiki.openstreetmap.org/wiki/Key:step_count. This is why I would say steps=* seems to be a former/similar tag for step_count=* (used on 60931 objects worldwide). On http://www.hotelroomsearch.net/im/city/bayrischzell-germany-3.jpg the handrail is visible. If Candid remebers steps on the way I would prefer highway=steps for the way and the removal of steps=yes because highway=steps is well documented in wiki and steps=* not. @Candid: Do you agree?
Regards 
Andreas
