I have mentioned before that the values OSM documents for the landuse key, while good, are incomplete with the great richness by which the world recognizes and categorizes these. Here, Mateusz mentions a "triple" where residential, industrial and farmland exist together (or perhaps "double" where the latter two are blended, a certain kind of "single" activity, so when the residence is added, this makes two distinct landuses in total). I myself have mentioned what are locally known as "residential / agricultural" areas, which I characterize as a "live on family farm." These consist of a residence (house) and small (one to ten hectares) or medium-to-large (ten hectares and larger) areas where a wide variety of agriculture either can or might take place. Some areas are substantially tree-covered and give rise to wild mushroom gathering, what I am told is a "fruits of the forest" activity, not "farmland." On these (especially in clearings, grassland/meadow areas), I often find landuse=greenhouse_horticulture, landuse=orchard and landuse=vineyard areas which "crop up" and appear in imagery. Because OSM has specific tags for these, I tag them as I see them. However, should the entirety of the underlying area be tagged landuse=farmland or landuse=residential? The truth is, "they are both," but OSM hasn't a landuse=live_on_family_farm_that_gives_rise_to_tree-planting_viticulture_and_hothouses tag. Getting the entirety of the world to agree upon values which seem very highly locally-dependent and articulated seems difficult. The alternative is to have our renderers only approximate the tagging mappers are encouraged to "shoehorn" into, given these many, often subtle, landuse distinctions. Another complicating factor is "actual landuse" vs. "potential landuse," (does take place vs. can or might take place) where some say to "tag only what is actual." Others see this approach as a removal of land rights, further muddying what OSM means by landuse. These issues truly are complicated, I believe it is easy to agree.
