-1 
Except for Background images, gridding, drag-and-drop helpers, etc.
It should rather be a PlayField (as it comment already states).

Also, be wary of the "rename then subclass" deprecation, because if certain projects extend the deprecated subclass (And a lot do for PasteUpMorph), those extensions will never be used in typical circumstances.

(This also bit me with the ContextPart depercation… Certain tools that hook into debugging stuff via ContextPart extensions no longer work as no ContextParts will ever be around. Oh well..)
