How much of that is due to the git CLI and how much of that is inherent flaws with the git VCS?

I know git (the VCS) can become a bottleneck with massive monorepos at the scale of Linux or Microsoft. But is anyone likely to port them to something new just to be a little more agent friendly? And if the goal of this new VCS was to make life easier for large monorepos (for humans as well as agents) then why doesn’t the author mention that on the project’s website? Because that’s exactly the kind of thing that might make this an easier sell to project teams.
