The launch criteria for Take a Break included balancing the known upside against changes to ecosystem usage metrics

"The launch criteria are… 3. Balance ecosystem effects: The balance between the known upside of the solution and changes to ecosystem usage metrics. We'd expect some level of effect if there's material usage." "We recommend prioritizing our analysis of experiment data on #3" "For #3, we will: - Disregard variants with material ecosystem regressions: - Time spent: regressions < 0.2% - Sessions: regressions: < 0.2% - Creator watch time: regressions < 0.5% - Balance ecosystem effects: - If there are multiple variants at this point, then our choice of the best variant prioritizes trading off big reductions in ecosystem regressions for small reductions in adoption."
