 doc:
   - audience: Runtime Dev
     description: |
-        Add the option to use remaining weight on idle for processing enqueued messages.
-        This will increase the chances of the messages enqueued during inherent extrinsics to be processed in the same block. 
-        New config types is added on the message-queue `Config` trait:
-        - `IdleMaxServiceWeight`
