This is always the first thing I look for in the new version announcements for big blogging platforms.

Would be amazing if I didn't need to know a completely separate technology and/or hack together bridges/site "staticizers" in order to have a quite basic functionality (the site be 100% static when no back-end dynamic interaction is needed).

That said, there are third party plugins for WordPress that do this. Don't know about ghost, but my hopes are for first-class support for this.
