Does any existing publication do this? Because providing both shortened and full URLs like this sounds like a great (i.e., retrospectively obvious) way to achieve a balance between "UX" of the magazine and longevity.
Yes. CrossRef.org, which is the registration agency for DOIs (digital object identifiers) does this for URLs in basically the entire scholarly publishing industry. This combats link rot by ensuring that the database of metadata is always up-to-date, and with other initiatives.
