Build logic like the above example creates challenges in resolving declared dependencies, as reporting tools will display this dependency as if the user declared the version as "2.0", even though they never did.
Instead, the build logic can avoid iteration and mutation by declaring a `preferred` version constraint on the dependency's coordinates.
