I don't think that's the case.  One of the rationales for using NSCell and subclasses was that they were lightweight.  Switching to views is somewhat heavier-weight but enabled by much faster computers since the old days.  In other words, the old NSCell-based approach was, if anything, even more amenable to lazy loading.
