Is there a way to ignore a property to be serialized if missing from schema?

Nobody has claimed this yet.

I'm trying to support easier schema evolution so that code with new properties can be deployed before the new schema is published.
out of the box, if you have an extra property to be serialized that doesn't exist in your schema, it will through an error `cannot determine codec: "{field_name}"`.
Is there a way to make the serialization more lenient and just skip any property that is NOT defined in the schema?
In the Pydantic world, it would be equivalent to the `extra: ignore` property.

I couldn't see a way at first glance.
Please advise

Start by tracing the serialization path that reports `cannot determine codec` when a property is absent from the schema. Determine whether unknown properties can be skipped without affecting defined fields, and check the existing schema and codec handling around that path. Done means serialization succeeds while omitting properties not defined in the schema.
