Splice[1] Studio[2] used to be version control for music software (from about 2013-2021). You could browse Ableton Live (and a few other DAWs) projects and see the tracks and rendered versions each time you saved, add metadata etc. They pivoted into the more profitable sample discovery and sales business later and dropped the less profitable studio product.

I expect over the next few years that the DAWProject[3] open source protocol for exchanging between DAWs could make it possible for some of the ideas of splice come back without having to rely heavily on undocumented binary formats.
