 There are discussions to extend dir-spec to serve recent, non-current
 consensuses and votes (#21378). As of now, only the most recent, current
 consensus and votes are available, as well as the next ones, 5-10 minutes
 before they become valid.

 This extension is fantastic news, because we currently rely on CollecTor
 to run once per hour. And if it doesn't, we'd be missing the consenus and
 votes from that hour. We can compensate temporary failures to some extent
 by having two CollecTor instances running and synchronizing missing
 descriptors. But ideally, we'd be able to fetch previous consensuses and
 votes from the Tor directories.

 This is currently blocking on #21378. But as soon as that ticket is
 resolved, we can start extending CollecTor to fetch recent, non-current
 consensuses and votes.
