if you have x number of detached residences occupied by offices,
it is not a landuse=residential

> it follows from the detached residences inside

if all plots have fences or hedges entered in osm, or if
the buildings touch each other, an algorithm allows you to build
the landuse=* of each building and merge the identical landuses
but sometimes you don't have enough info to find the value
of the landuse, so you don't have the info to create anything
other than a landuse=yes around each building 8or a place=plot)

but this is not reality... plot boundaries can be absent from osm...
or a large enough plot can have commercial activity on one side
and residential activity on the other -> 2 landuse=* in osm

take a location that is not too dense in information in osm
and draw what your algo could produce as landuse=*
I think this will shed some light on the number of times the information 
is not detailed enough in osm to do what you would have wanted.
or maybe come back with an interesting example that will motivate 
someone to do something with it (assisted contribhtion for landuse
or rendering or whatever)
