I would replace it.

The compiler needs data files for all supported versions, with
old_versions listing the, well, old versions. It then computes
deltas, expecting that they should mostly consist of new
assignments (i.e. characters unassigned in 3.2 might be assigned
in newer versions). It detects all differences, but might not be
able to represent all changes.

The latter. It doesn't really need to be that clever: primarily
just a compressed list of "new" characters is needed, per version.

You couldn't use the space savings then, I suppose.
