In my view, this is a pretty ideological posting. The discussion and solving of "problems" should come first and THEN we can decide about our adherence to Hennigian (or any other) system. In a case we will first decide about our belief in a particular taxonomic school and only then discuss the relevance of the "problems" we are losing the scientific background. Indeed, labelling the methodology as 'strictly phylogenetic' etc. is a pure marketing only.

Best regards!
