Splitting the abstraction is never cheap and quick, mostly because of politics. With duplicated code you often can assign a single responsible owner to each duplication.

However, once abstracted, the code may suddenly be used by a number of different teams. You will need to get this work on their roadmap, increasing the friction to get this done. In many companies, this will also end up in endless discussions about the new approach.

This is a good point. Following Conway's Law, a team may choose to duplicate code or do thing theoretically sub-optimally simply to avoid having to deal with other teams.

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.
