No.  Cladograms are of critical importance in determining genera, by
establishing which species form monophyletic taxa.  Whether or not
this cluster of species constitutes a single genus or multiple genera
is then matter of taste.

Yes, cladograms shift about.  No big deal.  And AFAIK no phylogenetic
analysis has recovered _Apatosaurus_ (including _Brontosaurus_ and
_Elosaurus_ type specimens) as anything other than monophyletic.
