It's also advantageous to provide some low-level services that provide a convenient API to access things, such as HTTP remote requests and/or logging. Doing so will allow you to create unique characteristics that you or your team like to work with when interacting with low-level APIs. For instance, maybe your backend API requires a unique header to be set in addition to a special authentication header for each request. Creating a low-level wrapper around an HTTP service will allow you to isolate those unique characteristics and provide a consistent API for your app to interact with, to guarantee all the API calls are enhanced with what they need in one place.

Additionally, your team may desire an ability to funnel all the logging code to a third-party log analyzer (for debugging or other performance-related metrics). Creating low-level wrappers with the lean code around some framework services will allow your app to adapt to these potential needs quickly.
