I think it depends on whether the library you're using is well designed and doesn't require contorting code around it. If it's a simple integration I don't see much of a point in abstracting it but if dealing with the library is painful on some level you'd maybe get some benefit from doing so. That being said this is somewhat orthogonal to the issue you're describing
I do have a *Utils module to wrap some calls to the AWS SDK but it’s not to protect from “lock-in” it’s a classic DRY principal of putting a code snippet in a function so I don’t have to remember how to do it every time.
