Because the Growth team tends to deploy features to pilot wikis only, we have a fairly large set of feature flags. Many of those are set to true at all wikis already (since the features scaled up sufficiently), but we still need to spend some time ensuring they are properly respected in the code, in case we ever decide to set the flag to false again. Most recently, this came up in T367330: GrowthExperiments: Do not expose configuration for unavailable features from Community Configuration, where we implemented a special case for "levelling up disabled", even though we do not have levelling up anywhere.
If we remove some of our feature flags, we will be able to simplify our code, making it easier to maintain in the future. For this reason, we should review that all of our feature flags are still needed, and consider removing them if possible. The full list of our feature flags is below:
