  We observe that a recent theorem of Sato, Toms-White-Winter and
Kirchberg-Rordam also holds for certain nonunital C*-algebras. Namely, we show
that an algebraically simple, separable, nuclear, nonelementary C*-algebra with
strict comparison, whose cone of densely finite traces has as a base a Choquet
simplex with compact, finite dimensional extreme boundary, and which admits a
continuous rank function, tensorially absorbs the Jiang-Su algebra Z.
