It is a good thing in some cases for a couple of reasons - first, off the shelf libraries often do a lot more things than are needed for the project at hand which can have the same effect that adding extra lanes to a highway does on traffic - more effort in the same space that could have been avoided. Second, OTS libraries can be opinionated, which winds up bending the existing codebase in ways that aren't optimal or aligned with the other code in a given ecosystem.
