The idea is to be able to add specify that a post is part of a serie, and offer automatic navigation to other posts fro the same serie.

It gives strong coupling between multiple posts.

I know it exists at least on dev.to :

I have made something for our internal use case, and added i18n for english and french, but I am not 100% percent I choose the right path.
