> in my opinion, the majority of projects developed in-house in an organization by a dedicated in-house software engineering team, would be better off following the guiding principles in Why Google Stores Billions of Lines of Code in a Single Repository and rather using something like SVN rather than git.
Mmm no thanks! In any case there's no reason you can't use Git itself as a monorepo! You don't have to inflict SVN on people for that.
Well, the one reason would be to avoid having to deal with Git-Apostels who insist on using git "the right way" instead of how you tell them to. If they cannot learn the 3 or 4 ways of calling svn, for sure they cannot use git the way you want them to.
