### Flags on the path to feature launch and flag deprecation/removal

- DASHBOARD_VIRTUALIZATION

### 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.

## Deprecated Flags

These features flags currently default to True and **will be removed in a future major release**. For this current release you can turn them off by setting your config to False, but it is advised to remove or set these flags in your local configuration to **True** so that you do not experience any unexpected changes in a future release.
