It doesn't seem that there are any published releases for this project, although there are four tags.
Does that violate the guidelines?

Does it make sense to include this project now, given that it's still in the pre-release stage? Previously, we to hold off on including projects labeled as "work in progress," "undergoing a rewrite," or similar. Should we take the same approach here?
