So, you're proposing that we store block checksums in each
representation, so that when we diff two representations against each
other, you can skip past the windows which have matching checksums.

If we stored plaintexts as deltas against the empty source, we could do
this with (drumroll) window checksums. Which CMike just eliminated from
the schema. Cue Alanis Morisette song here.
