December 2025 (databricks/sjsonnet): Implemented a Custom Val Type Materialization Mechanism, enabling custom Val types to supply their own materialization logic. This closes the Materializer gap for non-standard Val implementations and broadens extensibility for advanced users and extensions. The change was contributed in a PR (commit a6b388630f4e2ef31330ab32ecdca3a4a7f01480) co-authored by Stephen Amar and He-Pin (kerr).
