How is this an argument? You merge the unforked projects and its the equivalent to multirepo. I don't follow the argument at all.

...I started writing rebuttals to the others but I guess when your argument is "yeah you can do it right but you _could_ do it wrong and I have defined the question in such a way that we err on success for multi-repo and err on failure on mono-repo" I can't really fight that.
