Which feature have I mischaracterized?
I've seen low code vendors claim you can do reviews in git... but its an experience not unlike reviewing changes to a generated hibernate or entity framework xml. Its not really reviewable
I frankly haven't used vba for a couple decades at this point, but if you dig deep enough its pretty much all there. Combined with sharepoint/etc you can probably get a lot of the UI to be web facing as well.
There’s a git extension, git-xltrail, if you want to use Excel with git.
