Thanks, this is super helpful. For us, we are pretty heavy with manual QA, and for work that can't be wrapped in feature flags, we'd still have to test a fair amount before merge, but at least it wouldn't have to be for every PR.

For post-release QA, at what point do you close the story? After all the subtasks are merged/deployed? Or later, after QA is done and they turn on the feature flag?
