Sure, as a co-developer of mkgmap (1) I am very familiar with the process of consuming OSM data. I also understand that it requires years to establish a new tagging scheme. I think one problem here is that you list these arguments for a change that happened far back in history. 1) Most of the ~100 nodes with the highway=traffic_calming and no traffic_calming=* tag were last changed before 2014, 2) most of those nodes with both highway=traffic_calming and traffic_calming=* were first mapped with highway=traffic_calming and later the tag traffic_calming=* was added. 3) nearly all traffic_calming=* mapped in 2015 do not have the highway=traffic_calming=* tag. I don't want to stop or change this process (although this discussion seems to lead that way). Chris Hill-6 wrote > Diversity in tagging is not a problem.

Well, of course diversity in tagging is a problem. For each data consumer and for each new mapper who tries to find out how to map something so that their preferred OSM-data-consuming-program is understanding the data. The problem exists and causes lots of work. Diversity in tagging is also a basic feature of OSM and I think it is a good way to find out how real world elements can be described with abstract attributes. My understanding is that this is a process and that the result of the process can be a well established tagging scheme with few special cases - I think traffic_calming=* is one of those - or total chaos as we have with highway=path/footway/track or residential/unclassified.
