I think you should re-read the OP's original link again. Aether is not just an SSG, and its admin interface provides a CMS interface.

And I'm afraid your definition of a CMS is your own, and not the consensus. A CMS doesn't need to consume external sources, it can be self contained content.

”The integrated static site generator isn't bolted on, it's fundamental to the design.”

A Markdown editor in an admin UI does not promote the system to a CMS, although I could be skewed towards enterprise systems here…
