What I meant is that modelform_factory() also has these parameters:

localized_fields is a list of names of fields which should be localized.

labels is a dictionary of model field names mapped to a label.

help_texts is a dictionary of model field names mapped to a help text.

error_messages is a dictionary of model field names mapped to a dictionary 
of error messages.
field_classes is a dictionary of model field names mapped to a form field 

If we accept the patch for widgets, then are we headed down the road of 
adding support for the rest of those arguments? Customizing a form directly 
rather than indirectly via the view seems like better design to me. It 
doesn't require adding features to ModelFormMixin as they are added to
