 Replying to [comment:6 joehoyle]:
 > Ah, sorry missed that we needed the type to call
 `update_object_term_cache`. However, I don't see why we can't do
 `wp_cache_add($object_id, $terms, $taxonomy . '_relationships');` it's
 going to read that exact cache key via `is_object_in_term`

 The current behavior is '{$taxonomy}_relationships' will only include
 relationships with post type objects. Updating the cache in
 `is_object_in_term()` will change the behavior by adding non-post-type
 objects. I'm not sure whether or how this change will manifest itself, but
 surely it'll cause bugs somewhere, so I want to be conservative about
 modifying what gets cached.
