The DataStore doesn't necessarily need to know about the versions to be
able to better compress the data. For example, if a data store
implementation splits up the binaries into smaller blocks, it could re-use
blocks. Or the implementation could detect where to best split (using a
rolling checksum similar to rsync). In my view, there is no need to change
the data store API to better compress the data.

That's also an option.
