Comment:

 A "term_id" is not actually unique to a term in the general sense. It is
 unique to a single, unique name and slug pair. But it may exist in
 multiple taxonomies. That's the point of the term_taxonomy_id. So, "Apple"
 may be in the fruit taxonomy and the company taxonomy. But metadata stored
 against "Apple" doesn't make sense — you'll want to store it against
 "Apple" + fruit or "Apple" + company.

 This is why our API passes around term_id + taxonomy to uniquely identify
 a term, as together they are synonymous to term_taxonomy_id.

 This is a duplicate of #10142. There it is outlined why we have not done
 this yet, and what we'll need to do first to be able to do this in the
 future.
