I agree with you that this classification does not seem very relevant,
at least not as _the_ classification of OO languages;  but relatively
many authors still refer to it.  Peter Wegner has later written a truly
"wide-spectrum", wide-view article entitled "Concepts and Paradigms
of Object-Oriented Programming";  it fills practically the whole
first issue of ACM's OOPS Messenger (August 1990).  I was surprised
that he still upheld that classification somewhere in the new paper.
