Use case / explanation: 

An application is hosted on a cluster of servers behind a non-sticky load
balancer. It is updated daily. Even though all servers are not updated
instantly and two versions of the application co-exist for a while, it is
possible to update the application without risking to have an out-of sync
version of the application (e.g. manifest file and assets of the latest version
combined with a Master Entry of the previous version) or to need to invalidate
the cache to avoid such issues.
