IIRC another issue is large directories, changes to them store the entire directory for each commit, rather than just the changed file entries.

`restic` has a similar problem. The plan there, IIUC, is to split directory blobs using a rolling hash just list data blobs are, but progress is stalled.

We solved this in `bup` recently, which actually stores data in git packfiles, but of course the split tree layout is no longer really compatible with git (it looks like a directory with nested subdirs to git.)

How does that differ from the way Git stores files? (Which also are stored in full rather than just the differences – but the "packfile" structure delta-compresses the resulting objects.)
