Solution there would be to make the abstraction "opt-in", such that a team can elect to duplicate or abstract as desired. Also helps if the "main" abstraction is itself composed from smaller abstractions, from which downstream teams could then pick-and-choose rather than having to either fully abstract or fully duplicate.
