Of course it does (for me :-) ). What you present below isn't a phylogeny
(and then the monophyly of Gruiformes is in discussion...).

In a list as above, it does look clumsy. But in a cladogram, I think this
looks much better than
because it conveys more information (even if only about the "size" =
contents of Aramidae).
Maybe,but you shouldn't forget that everyday people don't work with
cladistics and if you have to put something like phylogeny in a book for the
masses it's much more comprehensible if everything's placed in ''niveaus''
of the same importance to avoid that people might wonder why some species
seem to have a far greater importance or status then other species.

Oh, I wasn't talking of such cases. I agree the 3 aren't monotypic just
because only one species each survives. (Though... what known extinct
rhynochetid is there? And what psophiids are there except *Psophia*? Real
questions, not rhetorical ones.)
Well there is this subfossil kagu,though I don't remember it's name as a
species.Furthermore,some include the extinct New Zealand adzebill (Aptornis
(or Apterornis)) in Rhynochetidae as well.
As for Psophia,I believe no fossil ones have ever been described,but they
must have existed obviously!
