New option will only include diffs in the "main" output unit for the provided builds. Only sub-library entities have an output unit. Libraries do not have an output unit because there is no code associated with the library itself and a single library's contents can be spread across multiple output units. Mutually exclusive with the 'package-only' flag because that one only prints libraries and 'main-only' includes no libraries.
