What is the use case of LibraryPresentationProvider instance?

Hi all, What is the use case of registering a LibraryPresentationProvider instance in plugin.xml file, e.g. https://github.com/go-lang-plugin-org/go-lang-idea-plugin/blob/master/resources/META-INF/gogland.xml#L147 .

Is it used for representing libraries in `Project Structure` > `Libraries` panel?

Thanks in advance :)
