Looks like humus is a component of soil. So I think soil covers it,

To me it is hard to imagine an area as permanently natural=bare_soil.
Wouldn't there always be some kind of vegetation within a year?
Not always.
Sorry to say but some soils have been so polluted combined with the
resulting soil erosion vegetation has taken some decades to come back.

I agree it could be considered as humus. The distinction between
organic soil and humus is ambiguous according to
https://en.wikipedia.org/wiki/Humus , but I think it is general
enough to target mostly organic soil.
Shall we consider to add this specification on the tagging? Or
would humus be considered as bare soil anyway?
Thanks

Organic without any mineral, would you still call that soil?

+1,
I also disagree that “soil can be organic or mineral”. It has
typically both, organic and mineral components, but organic
components are a hard requirement. Otherwise it would be sand,
or rock, or silt or clay or loam etc. (depending on grain size/s).
Cheers Martin
