KDE needs a single webpage that lists every website (domain, and subdomain) that is controlled by the KDE project as well as every site that is officially endorsed by the KDE project. I recommend https://www.kde.org/sitemap.php, or better, https://www.kde.org/sitemap This page must be linked to from the footer of https://www.kde.org/ and preferably from footer of the homepage of every one of the websites listed on the sitemap. Reproducible: Always
Can you give a reason why we need a sitemap?
According to this video https://www.youtube.com/watch?v=JlamLfyFjTA&list=PLKoqnv2vTMUOnQn-lNDfT38X9gA_CHxTo&index=2 from google, a sitemap can be helpful if we have isolated page we want to have indexed, a very large website or very frequent weekly page. I don't think we are impacted by any of the three conditions and building a sitemap for the current php website will be to much work, for to little gain.
