Enough time to debug tricky problems, e.g. 32 days of retention for source. Even if other topics and namespaces would have smaller retention, they should pretty much all still have some retention as the cache-readers of different services need to have something to fill the cache up from, maybe 16 days, or just simply the same 32 days. Readers do not cause subscriptions that would cause backlog to accumulate so backlog cannot be used as a solution.
