So for office, you're looking at files that are archive formats already. Maybe you could improve that a bit, but because of the compression you wouldn't be able to diff text edits better, just save storage. So it would perform about the same as git already does. And you could make it smarter so the prolly tree works better, but you could also make git smarter in the same way, it's not a prolly tree specific optimization.

For your UI editor I'd need to understand the format more.
