Actually I don't think that it could really impact current UI applications.
it could improve UI performance because bindings to objects are mostly
based on #perform:, But I doubt it could be felt.
But from other side in case of UI send sites will be megamorphic points
because "pluggable" UI components are used with most domain objects during
application runtime.
So my question was more in theoretical field.
