Switching dead links to the archive is a move to a dead end, instead of looking for

a) the new correct URL, as many links were just moved. b) alternative sources for the same fact.

An automated process can't reliably do either of those, while having the archive link available will make it easier for human editors to do both of those since they'll have the actual content of the dead link available rather than just what information is preserved in the citation (URL, title, author, maybe a short quotation).
