But that doesn't take into account the relative occurrences of the feature. Perhaps only 10 canal-mad people in the UK will ever use the "mooring" tag. Does that make the tag less useful/important/official/correct/anything than the highway tag which thousands of people use? If 25 people mistakenly use "highwey=primary" instead of highway, does that make it more correct than using the mooring tag? The database can tell us what _is_, but _is_ does not imply _ought_. We can either decide that OSM has no view on _ought_ (and just have a free-for-all), or we can take advantage of the accumulated mapping expertise of OSM participants and have a set of best-practice "ought"s. This is what we do now with Map_Features, some of which were carefully designed after considering several other tagging schemes for that feature type which seem good at first glance but turn out to have flaws.
