very much this. there's also a cultural understanding that libraries/fat clients are equal or worse in terms of maintainability compared to services. equal in the sense that you have to treat them like a service, worse because it's easier to mess up and you don't get to control your rollout strategy.

EDIT: Though while most teams have gone towards many smaller packages for their applications, I suspect that most would be better served by a team level monorepo. That gets you all of the benefits of monorepo locally and all of the benefits of manyrepo globally, and unless your project hits the ~200+ developer mark maintaining things will be stay tractable.
