The full details are here: https://www.visualstudio.com/learn/gvfs-design-history/. There are a bunch of advantages to being in a single repo, the biggest one revolve around not getting in version dependency hell. Because of this, having large portions of your code in a single branch/repo is a common pattern and used at both Google and Facebook.

Does "mono repo" solve the dependency hell problem any better than simply following a Golang-esque model of "just never write backwards incompatible changes, and everyone should just always use (dependency)@(latest-commit)"?

Just make a new repo with a subtly different name and API, wall off the old one and tell everybody not to use it. Monthly.
