Am I right in thinking that if there were suitable diffs available it

osm_rels?
This would not work because these tables are different depending on
the stylefile used.
Fully self-referential diffs would be good for one thing: no need to
fetch the unchanged nodes of a way to rebuild the geometry.
They would potentially be much much larger than the current diffs, so
that's a clear argument against them.
