Review Comment: For as long as you don't link the anchor or need it stable (language-agnostic), there is no reason to invoke `Sink#anchor()` directly. I would drop it. The anchors from the skin are a skin problem because we don't know anything about them at this stage. So dropping 307 and 310 seems right to me. -- This is an automated message from the Apache Git Service.
