Unlike git repos, "Bit repos" or 'independent components', can be maintained in a single Bit workspace (which can be source controlled as a single project using git, if that's something you want). You don't have to run between codebases. You 'import' (sort-of clone) whatever component you need into your workspace and maintain it as if it was part of a standard monolithic project. Multiple components, hosted on different Bit scopes can all be maintained in a single workspace.
