Nope.
The debate is not only about hierarchies. Hierarchies are just one kind of
associations in the Topic Maps paradigm.
Topic Maps are indeed the tool to escape the
verticality/hierarchical/classification paradigm in knowledge
representation !
What you call "lateral location" is tackled by the association concept,
allowing multi-dimensional representation of the "semantic neighborhood" of
a subject.
You have all the needed technology in XTM specification
www.topicmaps.org/xtm/1.0
Mondeca software www.mondeca.com is allowing various topic-centered
representations and navigation, based on both TM topological graphs
concepts.
