 * For convenience two predefined appender components are exposed on `InnerBlocks` which can be consumed within the render function:
 	- `<InnerBlocks.ButtonBlockAppender />` -  display a `+` (plus) icon inside a box which fills the Block preview. No default Block is inserted. Clicking the appender reveals the Block picker UI.
 	- `<InnerBlocks.DefaultBlockAppender />` - provides the default "auto-insert" functionality described above under `default`.
-	- `<InnerBlocks.HideWhenChildBlocks />` - will only render `children` if the instance of `InnerBlocks` has no child blocks (typically only at point of first insertion). Once a child Block is added the `children` will not be rendered (see example usage below)
 * Consumers are also free to pass any valid render function which provides full 
 flexibility to define a bespoke appender
