 ## Policy for new packages
 
-We no longer accept new provider-specific packages in this repo. For
-defining provider endpoints and provider-specific OAuth2 behavior, we
-encourage you to create packages elsewhere. We'll keep the existing
-packages for compatibility.
+We no longer accept new provider-specific packages in this repo if all
