That’s why I said it should fall on the daw. They can serialise their own settings, including the plugins used and its versions, and have a common interface for plugins to expose and restore a serialisation of its internal setup.
I dont think it’s trivial at all, but exposed with a basic ui it could be a killer feature.
Hell, as a POC even simply saving everything internally on each “commit” could be a UX improvement, so you can move easily between “save points” of the project without going the “V2_final_forreal folder” route.
An Ableton live set file is just a gzipped xml, so I can imagine some git hook that would unzip it before committing it to git. That way you can merge different branches, but it will surely come with its own limitations.

I'd be incredibly surprised if there is any DAW in existence that doesn't do this already.
But it has very little do with version control per se.
Ardour already has "snapshots" which work pretty much as you describe.
