I think, that we need specific use-cases for this. We can use standard kotlin serialization and easily move data between MP branches. But if we want to use serialized data externally, we need to be more specific. A lot of formats are supported by kotlinx,serialization, but it is not universal.

In future, we will want to use Appache Arrow.
