I'm always confused by the external links on the save code now summary page (https://archive.softwareheritage.org/save/#requests).
I think it would make more sense if the main links pointed to the latest snapshot on swh (when it exists), and have the link to the original repository in a separate column with an explicit external pointer (like we do on the header of archived repositories).
(This quirk doesn't seem to be handled by T2324 / T2325, so I figured I'd submit it separately.)
