That's nice as an abstract principle, but there are only so many hours
in the day, so we need to prioritize which limits we're going to get rid
of.  The 4-byte limit on individual Datum sizes does not strike me as a
limit that's going to be significant for practical use any time soon.
(I grant David's premise that people will soon want to work with objects
that are larger than that --- but not that they'll want to push them
around as indivisible, store-and-fetch-as-a-unit field values.)
