I like the simplicity. However, it is possible to rollout a feature flag only to a part of the user, e.g. a 1% canary release (cf https://martinfowler.com/bliki/CanaryRelease.html)?

If not, I'm not sure this brings more to the table than simple configuration changes that are rolled out through your next deployment, which should be frequent anyway, assuming you have continuous delivery.
