+The React team recently added a feature flag to stress-test Facebook components for potential incompatibilities with our experimental async rendering mode ([facebook/react/pull/11587](https://github.com/facebook/react/pull/11587)). We enabled this feature flag internally so that we could:
 1. Identify common problematic coding patterns with the legacy component API to inform a new async component API.
 2. Find and fix async bugs before they impact end-users by intentionally triggering them in a deterministic way.
 3. Gain confidence that our existing products could work in async.

 # Drawbacks
 
 The current component lifecycle hooks are familiar and used widely. This proposed change will introduce a lot of churn within the ecosystem. I hope that we can reduce the impact of this change through the use of codemods, but it will still require a manual review process and testing.
 
-This change is **not backwards compatible**. It will require library maintainers to drop support for older versions of React in order to support the future component API. Unfortunately, I believe this is unavoidable in order to safely transition to an async-compatible world.

-Assuming we move forward with the proposal, release (at least one) minor 16.x update to add deprecation warnings for the legacy lifecycles and inform users to use the new static methods instead. We'll then cordinate with library authors to ensure they have enough time to migrate to the new API in advance of the major release that drops support for the legacy lifecycles.
