Loqi ok, I added "Limitation: GUIDs on the web are not "G". While RSS & Atom assert that post GUIDs (and thus a h-entry uid) can be used to de-dupe entries (avoid new unreads) when a feed moves across domains, that assertion violates modern understanding and restrictions of cross-origin semantics, and cannot be expected to work. Assume such post GUIDs only work in the context of their domain." to the "See Also" section of /uid https://indieweb.org/wiki/index.php?diff=75685&oldid=75683
