Git VFS, to allow monorepos to be operable at enterprise scale (courtesy of Microsoft) is out there, as is Uber's white paper on ML to predict branch merge compilation success - an actual problem at enterprise scale. That doesn't cover all issues but every (huge) company's workflow is different, thus there's no "one size fits all" that's totally suitable - part of git's success is that it fits into whatever existing workflow a company already has. So I'm not sure the full suite of Google's tools would be at hit at all companies, especially anything smaller, and less dedicated, than. Google. Having a team to work on and another to operate, Bazle (and the internal Google project it springs from); not all enterprises are willing to staff that work, and definitely not as strongly as Google.
