I think that Andrew has answered your question. BATMAN is a pure mesh
protocol; it doesn't support filtering, aggregation, or overlapping
prefixes, and only limited support for multiple interfaces per node.
Pure mesh is an excellent choice for layer 2 routing, where there are no
overlapping prefixes, and little opportunity for aggregation or
filtering.

(In a pure mesh protocol, routers with multiple interfaces should
probably appear as multiple nodes; that is not done in BATMAN, seemingly
for efficiency reasons, a choice I am not quite comfortable with.)

Yes, and that's a feature. Layer 3 problems are outside the scope of
a layer 2 protocol.
