Why does this need to be a dependency? In my view feature flags are core enough not to be outsourced to a third party. Although, there are companies using libraries for "isEven" so there might be a market for it.

That's a fair point! Basic feature flags are just toggles, true and false. But they quickly become complex as you onboard new customers and scale. You need percentage rollouts to make sure things are working before everyone starts using the features. It only makes sense for engineers to spend time building actual features and testing them in production rather than spending bandwidth on building a feature flag management tool or managing the service for the same. This is a typical build vs buy debate. :D

I thought it's satire. Like "/dev/null as a service".
