Organization doesn't take into consideration parents from nested names
For hostgroup, in case of a nested hostgroup, the name is: hostgroup: Role/base
For organization, this is not the same. For nested organization names (Others/user), the exported name is only "user". This is not consistent with the hostgroup. Also I think it may lead to problems with hiera in case there is an organization "user" and one named "Others/user" (didn't test it).
