For a existing project we need to extend an event with a new refId.
The refId becomes the new identifier for an entity hence, we would
prefer to deprecate the event without the refId. This is all needed
because we discovered that the old identifier wasn't unique.
At the moment this is not possible, because the old events remain in
the event store.
My idea is to enable the deprecation of the event by using a snapshot
Is there already any progress on this feature?
