def transform(record)
  if parent_declaration_data.key?(:mutable)
    # hmmmm.... can we really just arbitrarily clobber this?
    # wouldn't that be surprising to calling code that passes in a record/model?
    # One use-case of this seems to be to reduce the amount of possible errors a command reports
    # by declaring that only some subset or none of the attributes are mutable.
    # However, we shouldn't react to this by clobbering the mutable state of the record because it might not
    # be a fresh record fetched from a primary key it might be an already loaded record/model from some other
    # context and that context might be surprised to learn that we've clobbered its mutability status.
    # Solutions?
    # 1. In the case of models, we could duplicate the model if the mutable value is different.
    # 2. But what about entities? We almost need some sort of proxy entity that tightens the mutability?
