Cursors

        In order to put the ability for the ZZ structure to refer to
        any cell, we have to go through convolutions (use more than
        one cursor dimension, etc.).

        The resulting cursor dimensions are such that they should not
        be used by anything other than the cursor API, which kind of
        breaks the nice idea of gzz.

        Many-to-one references always cause this kind of thing in zz structure.

Slices

        Lots of problems in loading different slices when there are cursors,
        or anything other than just basic user-visible structure

Consistency

        As in cursors, if you have some higher-level structure you want to
        use for a view, keeping it consistent by your rules is not simple.

How do you mean?

That's how I've seen these three articles: the birth of something
that's been maturing for 2-3 years.
