I would like to suggest that Citoid automatically archives pages when they are used in a reference. Yeah, I know, you have a very long to-do list, but put this on your eventually list.
Topic on Talk:Citoid
Do you mean "automatically finds the archive URL from the Internet Archive and makes it available" or something else?
Yes, or, automatically creates the archive would be even better. We could potentially eliminate the scourge of dead links.
"Creates the archive" meaning "asks the Internet Archive to archive the URL"? Or are you asking for WMF to archive the Web (in which case I believe the answer is a very clear "no" from Legal, as repeatedly discussed over the last few years).
The internet Archive is already "crawling all new external links, citations and embeds made on Wikipedia pages within a few hours of their creation / update." Only enWP, it seems (and caveat robots.txt).
The french WP even automatically adds an archive-link to wikiwix on all reference links.
The rest is rotting away.
PS: Both cite_web and cite_news have parameters to use "archiveurl=" and "archivedate= ".
