I think the tendency to go with a paradigm which appeals to the intuitive
understanding of the intellect.  There is something significant there that
can be of vital importance, and value to computer science and software
engineering, imo.  It is this intellectual appeal, which underlies the
desire, and advice to embed, and layer OOA (most recently Rumbaugh in
JOOP, but also Booch and Jacobson from the past) as the primary
orientation of OOD.

Right, and this is why OOA holds such an important place.  The easiest
path is doing good use case analysis (a la Jacobson et al in OOSE, and
Wirfs-Brock), and then developing a good architecture.  While these two
things are often modified during iterative, and incremental process, doing
them right during the initial period of the project allows developers to
move forward, and make progress in the most effective, and efficient
manner possible, imo.
