I agree here. I've actually never heard the term continuation used to describe a divergent fork. MkDocs might be unmaintained now but it's still licensed, which doesn't change or expire over maintenance issues or lack of activity. (I'm not arguing against the greater good of keeping MkDocs going, it's awesome and I've used it more than once, but a licensee doesn't have rights to "continue" MkDocs - that's up to the copyright holder, the remedy for a user is to fork under the terms of the license).
