is that usefulness or convenience?

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 
classification ...

Kleo,

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 
system. 

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"?
