It’s fine for revisions history. I can see every published changed I’ve made going back 2 years when I created the site. You can actually use Takeout to get the raw css and html of the site if you wanted to as well. Although I wouldn’t consider it a user friendly process to do so. No real friendly way to export individual pages either though, so I couldn’t easily send my post to like a PDF for instance unless I printed it to PDF through the browser print functionality.

I liked it though because it gave me an easy way to create a consistent looking website that automatically sizes itself for any device without need for any hassle on my part.
