    get_object_or_none() now uses a TypeVar to type the returned object
    
as an instance of the provided model, preserving that type. This ensures
    
we don't end up with an Unknown type that we then have to manually map
    
to a type.
    
 
    

    





  

    
 
 
    
  
    Unit tests pass.
    

    Verified the typing of the returned object was correct when using the
    
function.
