Ah, right.

This applies however to gzipped files or single-file zip files, and not zipped files in general: a zip file compresses each file individually, so unchanged single files inside of the zip will deltify reasonably well, as opposed to unchanged single files in a .tar.gz file.

But that's a minor point not relevant here, and of course you are right. I just somehow did not register that "store the odf files" was supposed to mean "get checked into git in numerous versions".
