form data no longer copied?

README says:

Django Method Override will even copy over the form data to request.PUT

https://gitlab.com/localmed/django-method-override/blob/v1.0.3/README.md#L45

It seems that this feature is not working with django-method-override==1.0.3 w/ django 1.11. Is this feature removed?
