 ### Flags retained for runtime configuration
+
+Currently some of our feature flags act as dynamic configurations that can changed
+on the fly. This acts in contradiction with the typical ephemeral feature flag use case,
+where the flag is used to mature a feature, and eventually deprecated once the feature is
+solid. Eventually we'll likely refactor these under a more formal "dynamic configurations" managed
+independently. This new framework will also allow for non-boolean configurations.

 - [29264](https://github.com/apache/superset/pull/29264) Slack has updated its file upload api, and we are now supporting this new api in Superset, although the Slack api is not backward compatible. The original Slack integration is deprecated and we will require a new Slack scope `channels:read` to be added to Slack workspaces in order to use this new api. In an upcoming release, we will make this new Slack scope mandatory and remove the old Slack functionality.
 - [29798](https://github.com/apache/superset/pull/29798) Since 3.1.0, the intial schedule for an alert or report was mistakenly offset by the specified timezone's relation to UTC. The initial schedule should now begin at the correct time.
 - [30021](https://github.com/apache/superset/pull/30021) The `dev` layer in our Dockerfile no long includes firefox binaries, only Chromium to reduce bloat/docker-build-time
