A team wants to use the Tasks extension for long-running operations. What does the specification require?

選択肢

1. Both sides must support it and advertise it in the extensions field of their capabilities; it is disabled by default.
2. Every conforming SDK must implement it.
3. Nothing beyond upgrading to the 2026-07-28 revision, because the extension was folded into the core protocol in that revision, which is why the specification lists it among the notable capabilities of the base protocol.
4. Only the server needs to support it, since the client merely polls.
