Knowing whether something just links in a C library and adds a wrapper, and how thick that wrapper around it is useful in knowing how ergonomic the API will be, and how easy it is to cross target. For example, if you want to run on musl with a statically linked libc, then a library which is just a wrapper around a C shared library which depends on glibc is a non starter.
