Google’s Pascal Birchler, who has been with Google since this past January, but worked at WordPress since 2014 prior to that, published a new project where Google and WordPress want to integrate basic XML Sitemaps in WordPress Core and introduce an XML Sitemaps API to make it fully extendable. This will make it so WordPress has XML Sitemaps out of the box. Will this replace Yoast? No, in fact, it says “This post proposes integration of XML Sitemaps to WordPress Core as a feature project.
