No question, that was a good principle; but in practice there were or are very few places where they were used, yet far too many variants provided, some with awkward side-effects on the lists. I've no objection to one age_page_up() and one age_page_down() (though I do find the term "age" unhelpful here), inline or macro, but even so a lot seems to depend on where and when we initialize it.
