For internal purposes, we use binary formats for their brevity.
We use the `Serializer` abstraction to separate the actual implementation of serialization from its uses.

When sharing data with external tools, we use JSON.

## 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.
