Although the test cases I reported in this bug are indeed fixed in 7.3
(no extra unnecessary degree 3 processing), the much larger system from which
these examples were derived still exhibits the problem.  That is, in this
larger system touching a class still causes degree 3 processing on many
classes.  In this case, touching the original class (source/reticle_view.e)
causes degree 3 to be done on 129 classes.  Touching a different class
(source/reticle_view_element.e) causes degree 3 to be done on 482 classes.

Perhaps I should give you the full system, but it is a *lot* of classes.
