   Also, I noticed another potential con: we do mention UUID in the pyarrow extension type examples.  If uuid was accepted that might weaken that example.  However, the extension type example supports round trip.
   
   The original StackOverflow issue could almost be solved by an extension type except:
    * There is no way to tie an extension type into the inference logic
   
   The issue could also almost be solved by a pandas UUID extension type except pandas read_sql_query supports dtype but not a type-mapping mechanism that would allow a pandas UUID extension type to automatically be used if the column type was UUID.
