I think there's value in making the Maven lister support more Maven repositories than just Maven Central, even if we focus on Maven Central as the first proof of concept.

makes sense. IMHO, it's good to have one issue per repository, since every repository will have its specific topics

if you search for source-release or src, yes, you'll find archivable sources
the only issue is that you'll not find many content...

I renamed the issue title to "Maven Central repository Lister" if the intent is to focus on this repository https://maven.apache.org/repository/index.html
