 It would be nice to be able to effectively short-circuit a terms query so
 that you could return results from an external data source (`WP_Query`
 already has a filter like this in the form of `posts_pre_query`). My patch
 would add a similar filter `terms_pre_query` into the `::parse_query()`
 method of the `WP_Term_Query` class.

 This is more a proof of concept than anything else, I'm not sure if it
 makes sense to leave the burden of handling term caching as well as the
 hide_empty and the pad_counts parameters on the callback function.
 Hopefully some more experienced contributors will have some better insight
 into that.
