I'm also curious how they managed to drive it into the Git project. Presumably there can't be that many orgs out there for whom git repo size is a bottleneck. My rationale there is that the Linux kernel has thousands of contributors and vanilla Git scales ok there. Maybe I'm being naïve about something?
The Scalar feature of git is answered prayer for devs at such companies where an average git status command can take upwards of 30s!

Obviously MS devised such tooling and here we are... but have others just been quietly doing similar internally and never showing it the light of day?
There are many large orgs that are using pretty large monorepos. Which surprised me.
