[Taxacom] paraphylophobia again

The general problem is knowing when to stop and move on to something
more productive. Take the Strepsiptera problem, for example. A huge
amount of time and resources goes into trying to work out the
phylogenetic position of Strepsiptera within Insecta, but it cannot be
conclusively solved until a fossil is found which is half-way between
a strep and something else.
The Reptilia case is different because progress was possible, and the
results are pretty conclusive, and yet just about everybody still uses
"Reptilia" as if it were a class alongside Aves and Mammalia! The
formal reclassification would be messy, but ...
Perhaps we should use an unranked phylogenetic classification above
family-group level - that would make some things easier. However,
there is a move to regulate such names by the ICZN, e.g.
Dubois, A. 2009: Incorporation of nomina of higher-ranked taxa into
the International Code of Zoological Nomenclature: the nomenclatural
status of class-series zoological nomina published in a non-latinized
form. Zootaxa, 2106: 1-12.
Whichever way it goes, I certainly wouldn't want phylo- classification
to take over completely! We need to save Linnaean binomials at least,
and probably family-group names too ...
