@jamesbond - That article seems to describe the ability for Webflow to generate a sitemap for your site, which is something Bubble apps have been able to do previously (Bubble also had the ability to use your own sitemap instead).
The new feature here is to fill the sitemap with dynamically generated URLs when you have a page that is assigned a data type. The Webflow help article doesn’t seem to point to something similar, so not sure if they do or don’t do this, but we certainly think it’s a useful feature 
Also, note that this feature has been rolled out! Check out the post from Grace here . Thus, closing this topic about alpha testing. Thanks to all our volunteer alpha testers!
