Exposing streamable resources, whether remote network I/O or local data sources, allows your extension to hook into the core data manipulation functions and avoid reimplementing the tedious work of descriptor management and I/O buffering. This makes it more useful, and more powerful when placed in a userspace setting.

The next chapter will finish up the streams layer by taking a look at filters and contexts that can be used to alter the default behavior of streams, and even modify data en route.
