 ### Summary of changes
 
+Creating a config entry with a unique ID already present in the registry is deprecated, and will now log a warning.
+
+### Details
+
 When a config flow creates an entry with a colliding unique ID, the old entry is currently automatically removed and replaced with the new config entry.
 This can lead to unexpected behavior, and integrations should be adjusted to instead abort the flow.
