According to the document you shared<http://www.fao.org/3/x0596e/X0596e02a.htm#P1974_116516>, bare soil is mentioned in:
Primarily non-vegetated > Terrestrial > Bare areas
And within Bare areas, Bare soil is an available category, being distinguished by Bare rock whether the terrain is consolidated or not.
Within Bare soil, further classification is made depending on a "stoniness" percentage (5 to 40% Stony, >40% Very stony) and on soil macropatterns (II level).
I think this could be useful material for us to make a decision. natural=bare_soil targeting all the areas of unconsolidated ground material could be used whether or not a groundy area hasn't already a tag that suits better its representation (e.g. natural=wetland + intermittent=yes, landuse=quarry...).

If you are interested in reading some interesting thoughts about landcover classification, there is the FAO landcover classification system, thought to be useful globally:
there are only 8 main classes:
and you can easily determine them through a decision matrix:
1. primarily vegetated or primarily non-vegetated?
2. terrestrial or aquatic/flooded regularly?
3. cultivated/man made/artificial or natural?
then they add additional properties like life forms, crops, leaf types, climate, ...
>From the combination of these properties and classes, detailed land cover classes are determined:
Example of the formation of land cover classes
EXAMPLE: "NATURAL AND SEMI-NATURAL TERRESTRIAL VEGETATION" (A12)
Standard class name
Life form and cover
High closed forest
Continuous closed forest
Broad-leaved closed forest
Broad-leaved deciduous forest
2nd layer: LF, C, H
Multi-layered broad-leaved deciduous forest
3rd layer: LF, C, H
Multi-layer broad-leaved deciduous forest with emergents
PS: And the best: LCCS comes as a run time application, you do not need to have virtual basic installed !!11!!!
