With monorepos you don't have to manage PRs for 8 different repositories when adding a feature. In my experience it's hard to establish clear boundaries, regardless of repository kind. It may be more difficult to create features which are tightly coupled across multiple repositories, but people do it regularly. And when they do, you suddenly have to manage and maintain synced features across multiple repositories. In fact, the repo tool for the android project makes it quite easy to develop features across repositories, thus lowering the boundaries significantly.
