+(Note that several dependencies are already exposed to all extensions via `common-dependencies.gradle`.)
 
 Notice that we're using `compileOnly` instead of `implementation`, since the app already contains it. You could use `implementation` instead for a new dependency, or you prefer not to rely on whatever the main app has at the expense of app size.
