Comment (by boonebgorges):

 Idea seems OK to me, if it is in fact true that theme authors would find
 it useful. I don't fully grasp the utility of it, but I also don't fully
 grasp the utility of `is_multi_author()` :) Do you have examples of themes
 that are implementing this logic on their own?

 A couple notes on the patch:
 - `is_multi_taxonomy()` does not feel like the right name for this
 proposed function. `is_multi_author()` is checking to see whether the site
 has multiple authors. By extension, `is_multi_taxonomy()` would check to
 see whether the site has multiple taxonomies. But this is not right.
 `wp_taxonomy_has_multiple_terms( $taxonomy )` seems more semantically
 correct.
 - I don't think we need to have the underscore prefix for
 `_clear_multi_taxonomy_cache()`. We're moving away from this kind of
 naming convention.
