The problem of the no longer working links

After some time it is physiological that answers may contain outdated links.
And it is a pity.

I see a couple of identification strategies:

1. A script that actively runs across the entire database to detect inactive links (and after n failed attempts at different times of the day and on different days of the week) signals them.
2. A passive snippet that in case someone clicks on an expired link reports it to a server.

To solve the problem also I see a couple of solutions:

1. A script that replaces the expired link with that of the last snapshot (e.g. from web.archive.org) prior to the answer (or before the introduction of the link in the answer).
2. A dedicated review queue.

Is something already done/planned or can this be used as a suggestion, maybe to do a dedicated review queue?
