The expectation is that, while other libraries may not want to call gv_find_me, they may end up linking against it in order to use other libutil functionality. They almost certainly do not want to re-export gv_find_me.

This annotation is only correct while the containing library is built statically. If it were built as a shared library, gv_find_me would need to have default visibility (and thus be unavoidably re-exported) in order to be callable.
