I am unsure of the places that core uses the taxonomy_index.
However, I do know that its pretty useless unless you only care about node references to taxonomy terms.
The module taxonomy_entity_index exists to fix this problem for Drupal 7.
I would wager that since Entity API is in backdrop, you'd want this functionality.
