This is how Octopress/Jekyll/Ghost/other platforms work.

You have a backend which when you create a post just regenerates static HTML files, and then you just serve the static HTML Files.

There are obvious drawbacks like you mention.

Now that Wordpress is moving to node there is probably more opportunity for these types of security optimizations.

Don't hold your breath while waiting for WordPress so be based on node. That PHP code base will be around for most of our lifetime. :)
