Working on legacy/trac#30733 asn pointed out that there're no tests to check the changes in descriptors. It'll be easier to create these tests when: - sbws can use chutney (legacy/trac#33150) so that the test network lives longer than the 1st consensus - `RelayList` can be initialized with different consensus/descriptors and not only a controller (legacy/trac#29717) - have an external tool that check the generated bandwidth files in the Tor network and detects changes in the descriptors (legacy/trac#33152) Maybe we should include this ticket as part of legacy/trac#33121
