Isn't the argument here that Git is not good at mono-repos rather than that mono-repos suck? This seems true to me, but there are already other options that suck less if you want the advantages of a mono-repo.

I would also suggest that mono-repos work better with statically typed languages with module boundaries and visibility control. The problem of anything being able to touch anything else is not so bad when you can hide implementation details behind small APIs.

I have definitely felt some pain with having Ruby projects in a single repo using git, but much less so with Java projects using Hg.
