What
In auto mode, a separate checker (the classifier) decides whether actions are safe. It can send its requests on a message thread. If the API replies that threads are unsupported (server_thread_unsupported), this is no longer treated as a fatal error. A warning is logged and the rest of the session's checks are sent without a thread.
Why
The checker falls back and carries on instead of failing on that reply.
