First monorepo I worked on, we used separate compilation units for each 'module'. We paid a tax on build time but it added a bit of friction to adding new cross-module dependencies willy nilly.

I don't know how you maintain that arm's length separation if you don't have compilation units in your language of choice, and that may contribute to some of the muddiness in this kind of discussion. "It depends."

I think the private visibility and shared build chain that Bazel offers could step in here, in that it makes it harder to build a project without specifying every dependency, when combined with linting tools and clearly assigning code ownership...?
