Blaming the victim (the Linnaean System)

Ken, you confuse issues here. The idea of mandating the naming of all
clades or even a percentage of all clades obviously won't work and isn't
done (can you cite any recent proposal to do so?). That fact does not
lend support to your classification notions. If "dinosaur science" has
over-named its groups it has nothing to do with cladistic methods or
classification methods in general. Just because dinosaur or mammal
cladists may have exceeded your standard for a useful number of names
this has no effect my naming of insect clades, etc.

Most good systematists are aware that a useful number of names for group
is just as many it takes to identify biologically important and
hopefully stable clades. Name-mongering for its own sake should be
shamed and stuffed in peer review.

This issue has nothing to do with problems of formally naming
paraphyletic taxa, although you have often coupled it in your arguments
against "strict cladism" as some sort of fatal flaw of cladistics and
justification for your system. If that is not a strawman what is?
