Overview
When a new feature flag is introduced, it is set to false or “off” by default to ensure backward compatibility. We are not deprecating the current components but encourage all teams to use the new feature flag-enabled components in their products moving forward. Once the next major release (v12) is released in the future, these feature flags will become the default version of the component.
React
The development specifics for feature flags in React can be found in the @carbon/react framework.

Additionally, when clicking on the components details (C) in the properties panel, a description of the v12 feature flag, and a link to the component’s usage guidance is provided for more information in the Component documentation window (D).
