I suddenly imagine a zip format with built-in git. Does this already exist?
Basically a file-format that has built-in history, rollback, logs etc. Enabling all these "zipped XML" formats to get this feature "for free".
Could be as simple as adding the .git to the zip and ensuring the software that writes the content to the zip also runs the correct git operations.
But could also be a simplified subset and adding git-ability to the (de)compress libs and bins, which can operate on the compressed .git. Simplified, because it won't need networking/remotes probably not even branches.
Quick edit: hmm, I'm already ~1 hour late, the relevant thread starts at https://news.ycombinator.com/item?id=49327457
And Starcraft 2 data is just bunch of XML files.
But there's one material difference between StarCraft/Warcraft and Gimp: in Blizzard games, those were "zips" of heavy data files, notably read only data blobs. The game would read them, unpack in memory, and serve appropriately. Most of that data was key-value, text resources, or flat assets - images, sfx. With Gimp, we're talking highly structured data that's continuously being mutated. Very much not the best representation for that, even if you're just persisting it. They're only getting away with this because of SSDs - on spinning rust, you'd feel this.
(Also worth noting that, at least in StarCraft/SCBW, most of the files inside were custom, well-optimized binary formats. This predated the XML insanity of encoding data with 90%+ markup overhead.)
I meant zipping colloquially as in compressing an archive format. But you seem to get the gist of it ;)

Not just game files but also the map format for Warcraft 3 was a glorified MPQ (source: https://867380699.github.io/blog/2019/05/09/W3X_Files_Format).
So whenever you edited a WC3 map, you were zipping the current map into an archive. Much like the GIMP example. Of course, WC3 didn't use as many XML files, though SC2 changed that.
// At this point, I'd like to take a moment to speak to you about the Adobe PSD format.
// PSD is not a good format. PSD is not even a bad format. Calling it such would be an
// insult to other bad formats, such as PCX or JPEG. No, PSD is an abysmal format. Having
// worked on this code for several weeks now, my hate for PSD has grown to a raging fire
// that burns with the fierce passion of a million suns.
// If there are two different ways of doing something, PSD will do both, in different
// places. It will then make up three more ways no sane human would think of, and do those
// too. PSD makes inconsistency an art form. Why, for instance, did it suddenly decide
// that *these* particular chunks should be aligned to four bytes, and that this alignement
// should *not* be included in the size? Other chunks in other places are either unaligned,
// or aligned with the alignment included in the size. Here, though, it is not included.
// Either one of these three behaviours would be fine. A sane format would pick one. PSD,
// of course, uses all three, and more.
// Trying to get data out of a PSD file is like trying to find something in the attic of
// your eccentric old uncle who died in a freak freshwater shark attack on his 58th
// birthday. That last detail may not be important for the purposes of the simile, but
// at this point I am spending a lot of time imagining amusing fates for the people
// responsible for this Rube Goldberg of a file format.
// Earlier, I tried to get a hold of the latest specs for the PSD file format. To do this,
// I had to apply to them for permission to apply to them to have them consider sending
// me this sacred tome. This would have involved faxing them a copy of some document or
// other, probably signed in blood. I can only imagine that they make this process so
// difficult because they are intensely ashamed of having created this abomination. I
// was naturally not gullible enough to go through with this procedure, but if I had done
// so, I would have printed out every single page of the spec, and set them all on fire.
// Were it within my power, I would gather every single copy of those specs, and launch
// them on a spaceship directly into the sun.
//
// PSD is not my favourite file format.
