Airbnb has a version of this internally that was pretty awesome called Evergreen, based on the Uber paper as well.
I wish more companies would open source their monorepo infra. A well done monorepo is a huge force multiplier on a large organization, but the OSS world is lacking a lot of the infra so everyone starts from a painful place and works up or has a bad impression of monorepos. Google's Piper is another example where open sourcing or selling it would have done wonders for the industry. In an age of agents landing code very quickly piper has scaled very well since it was already at unimaginable commit velocity, meanwhile everyone else is trying to rebuild source control to keep up.
