Why not bite the bullet and go for a Kinman classification, which
includes both kinds of information? Or the intersection of Phylocode
with a "Paraphylocode" that marks grades by key innovations? The
Phylocode proponents believe that Linnaean classification can't
unambiguously specify clades; perhaps it can't unambiguously specify
grades either.
