LangChain ships a first-party integration that deliberately does not wrap the vendor's SDK
`langchain-typesafe` 0.0.1a1/a2 (merged 2026-09-17, released 2026-09-17 22:24 UTC) adds a `TypeSafeClassifier` runnable for TypeSafe's Jev model, plus experimental `ModelRouterMiddleware` and `AutoModeMiddleware`. The PR body is explicit that it implements the `POST /v1/systemone` contract directly against httpx2 rather than wrapping `typesafe-sdk`, reversing LangChain's standing policy, with the stated reason that wrapping was a response to limited maintainer attention and "agents are probably good enough to start shouldering most of the burden." If that trial holds, LangChain's ~100 integration packages stop being thin SDK wrappers.
