Did you consider making this a 3-0-1 schema instead of 4-0-0? To do this, the schema would be basically the same, but you would make recoverTableNames a non-required field.

A major change is disruptive for downstream consumers of the data, because they need to consume from a different table. In this case, you have not radically re-designed the shape of the data; you have only added a new field. So I think downstream consumers would prefer to have new events land in the same table as the old events.
