It's glorified in the sense that it's much cheaper. I have had small sites on s3 plus cf and have gotten a bill that boggles the mind because I could be hosting the content for free on netlify.
If you forget that then Cloudfront will retrieve the objects from S3 every time there is any activity on your site and your bill will go up really fast.
For how long? I remember I got something similar for AWS for a year. Hosted my Wordpress, year passed, then prices jumped up. I migrated to Netlify, rebuilding my site as a static one, hosted for free now.
