These members appear to concern clients that fall behind or reconnect and how session.replay_gap is handled by the gateway and CLI. One reports the CLI hanging on later turns after a replay gap was treated as a turn failure, and another proposes re-attaching instead of ending the turn in error; the outcome is not established by the titles.
