Not really. There's a big difference between changing the type name and 
changing the parameter name. You can freely change the parameter name without 
changing the type name. Also, you can overload on type names, allowing you to 
deprecate the old name and replace it with a new one gradually. You _can't_ 
overload on parameter names, so you _can't_ have a deprecation path with named 
arguments without renaming the function itself, which is _way_ worse. The 
difference between the two isn't even comparable.
