Practically every WordPress site with one of the top two SEO plugins (I'm not familiar with others) serves XML sitemaps with XSLT. It's used to make the XML contents human readable and to add a header explaining what it is.
Did you ever use a sitemap as a human? I've only ever seen it recommended for SEO, and search engines are perfectly capable of parsing sitemap.xml without needing it turned into some transformed format, or at least so was my understanding (been a while since I looked into sitemaps or SEO). It seems to only be linked in robots.txt, not to any humans: https://www.sitemaps.org/protocol.html#informing
Every (Wordpress) site with an SEO plugin should be fine, since the search engines can still read it and that's the goal of an SEO plugin
