There should be a seperate VC for this, because using git for stuff like that is a bit wrong.

Also many DAWs export their project files as binaries (like Logic) so Git wouldn't like that much in terms of Diff and Compression

The main issue is also maintaining multiple folders. Git can do submodules, but that means creating new gits, publishing, making new submodules etc which is a waste of time that a normal person would rather spend making _v2s, even though they're cloggy and messy
