Another question: a common pattern is to use (immutable) class variables as default values for instance variables, and only set the instance variables once they need to be different. Does such a class benefit from your improvement? A less common pattern, but which still needs to work, is where a mutable class variable is deliberately store state across all instances of a class...

This is really just a dictionary implementation. It doesn't affect any of the lookup procedures. If you trust that the dictionary semantics on its own isn't changed (which I believe is the case, except for key order), none of the dict applications will change.
