if cladistics gave stable and conclusive results, then all would be well, but it
ain't so ...
there is no a priori reason why classification needs to follow phylogenetics ...
phylogeneticists can study phlogeny and leave it to taxonomists to do

I can't answer your questions, but I am struck by the usefulness of this
discussion in pointing out that 1) classifications are most valuable when they
reflect our knowledge of evolutionary history and 2) the Phylocode is the best
way we currently have to reflect evolutionary history in a classification
The Linnaean classification system is woefully inadequate, as demonstrated in
this discussion thread. Why are we attempting to classify life in the 21st
century without including our understanding of the "tree of life"?
