The planned timeline is a usual finch deployment with a full release in M151. The experiment for 50% of Canary+Dev+Beta is already up and running for some time with no breakages detected.
I was asked for an explicit I2E (a thread mentioned in the summary) before experimenting on stable. The usual rollout is planned, however since the change is Incognito only I wonder if starting with more than 1% of stable would reveal more about the possible effects of the feature. If so - I assume I'd need more approvals from owners there. Let me know what's the best approach for you Michał On Monday, June 22, 2026 at 8:52:52 PM UTC+2 Dan Clark wrote: > Can you clarify the planned timeline for the experiment?
