I'm somewhat surprised that this isn't possible -- to the point where I'm wondering if I've missed this!

Anyway, if this isn't possible yet, it should be: set a product reference field instance to limit the products it can reference to different types.

This is for the use case where for product types A and B I also have node types A and B. It would save make it easier for the site admin to have fewer options in the autocomplete or select widget, as well as preventing mistakes.

function commerce_product_reference_field_info() {
  return array(
    'commerce_product_reference' => array(
      'label' => t('Product reference'),
      'description' => t('This field stores the ID of a related product as an integer value.'),
      'settings' => array('options_list_limit' => NULL),
      'instance_settings' => array('referenceable_types' => array(), 'field_injection' => TRUE),

It's definitely available nowadays, maybe it was back then too? Closing issue.
