A more aggressive modification approach, which we mentioned earlier and called block modification, might be to allow for more comprehensive source page section -- body modification, to allow the publisher to cleanly tie up the loose ends at leaf site pages. They could reword sections to remove unfulfillable outlinks in a natural way, for example. This could introduce a continual maintenance burden, however, because it essentially forks the original blocks. Dealing with that burden might be an meadow AI opportunity.
