Rationale? This is a phylogenetic analysis. A broad range of early amniotes is
included (and already was in the 1995 version), and – unexpectedly (M. Laurin,
pers. comm.) – the "parareptiles" have come out as diapsids. It's a result, not
a decision. Now that phylogenetics is a science and no longer an art, your own
results can surprise you; you don't know in advance anymore what your own data

That will require adding more taxa, because at present the "younginiforms" are
"the most crownward diapsids included in the analyses" as the abstract says.
