## Status

ACCEPTED

## Consequences

* The configuration cache serialization infrastructure should be used for all serialization.
* Existing usages of Serializer outside of this infrastructure should be migrated to use it.
* Existing usages of Java serialization should be migrated to use it.
* It is ok for Serializer to be used as a replacement for Java serialization as a migration step.
