I think Tom Lammers' question concerns the application of new phylogenies
based on molecular data, all else aside.  He is asking about new theory
concerning best practices when making a new phylogeny operational (i.e.,
when using it in a system of classification).

Judd et al. 1999 (Plant Systematics) mention this on p.42, including some
references to recent commentaries on this topic.
