For me the most important part is that in reality it is an area, not a way. Nodes makes sense as are much easier to map, but difficulty in mapping area and line is very similar, while area data is much more useful. For examples see https://www.openstreetmap.org/way/677266656#map=19/50.07839/19.96038 <https://www.openstreetmap.org/way/677266656#map=19/50.07839/19.96038> (amenity=bicycle_parking case) or https://www.openstreetmap.org/way/655025821#map=19/50.05589/19.92761 <https://www.openstreetmap.org/way/655025821#map=19/50.05589/19.92761> (amenity=bicycle_rental case). > > 2) Linear mapping is already allowed for bicycle parking and benches, > other street furniture amenities with similar dispositions. > > And I think that it should be avoided for bicycle parkings.

Current usage is 32 824 nodes, 1117 areas and 10 lines - see http://overpass-turbo.eu/s/H87 <http://overpass-turbo.eu/s/H87> and https://taginfo.openstreetmap.org/tags/amenity=bicycle_rental <https://taginfo.openstreetmap.org/tags/amenity=bicycle_rental> (4) Areas are much, much easier to process by data consumers. > > Perhaps the bigger question here is: the vast majority of stations are > currently mapped as nodes.
