Will all the chains under libs/langchain/langchain/chains be removed after 1.0.0?

[nan-wang]

Noting a lot of classes under libs/langchain/langchain/chains have been marked as deprecated, i am wondering whether the whole directory will be removed after 1.0.0`.

For example,

@deprecated(
    since="0.2.7",
    alternative=(
        "RunnableWithMessageHistory: "
        "https://python.langchain.com/v0.2/api_reference/core/runnables/langchain_core.runnables.history.RunnableWithMessageHistory.html"  # noqa: E501
    ),
    removal="1.0",
)

I don't have an answer, but I do have similar questions. The migration documents say we should be using langgraph instead, but still curious what the plan is for the use of the soon-to-be deprecated chains in their chains directory.
