   Hm, this might actually be a nice solution.
   
   Three questions before we continue:
   
   1. What about other canonical extension types, should they have the same 
behavior?
   2. If we change the behavior of the `to_pandas_dtype` in the `DataType` 
subclasses we are also changing the behavior for `to_pandas`. What would be the 
implications?
   3. Would it be worth cleaning up the docstrings for `BaseExtensionType` and 
its subclasses? As they are now inheriting from `DataType` without any mention 
of the extension type behavior.
   
   This are not meant as suggestions for this PR but are meant to trigger a 
more general discussion right from start. If we proceed this way we can make 
follow-up PRs any time.
