Unclear What "CCR" stands for and what specifically consumes this telemetry isn't stated.
What
The system init message sent at the start of a session can now include a startup_timing field carrying cold-start telemetry: named startup phases and counters related to resuming and hydrating a session. This applies to hosted CCR sessions; it's absent elsewhere.
Why
This gives visibility into where time is spent during a hosted session's startup and resume process, which can help diagnose slow session starts.
