The core telemetry ticket remains closed even though there is obviously a need for further discussion. Matt's argument for closing it - that "it is not within the three focus areas" - is no longer valid as telemetry is being discussed in direct relation to the Editor focus (Gutenberg), yet it remains closed. In the ticket Matt says telemetry is a "terrible idea" without further details and ends with "I doubt that anything actionable or useful will come of it that couldn't be obtained by non-data-collecting means."
