+9. `flavor set/unset` commands will no longer return the modified resource
+
+  Previously, modifying a flavor would result in the new flavor being displayed
+  to the user. To keep things consistent with other `set/unset` commands, we
+  will no longer be showing the modified resource.
+
+  * In favor of: Use `set/unset` then `show`
