Comment:

 In 4.1 we've begun to phase out shared taxonomy terms. See #5809, #21950.
 In a future release of WordPress, we'll have one-to-one correspondence
 between items in `wp_terms` and `wp_term_taxonomy` (and indeed, the two
 may be merged). See #30261, which blocks this ticket. So I think it's time
 to reopen and consider what the API would look like.

 A few initial thoughts:

 - Since term_id and term_taxonomy_id will be one-to-one, I think it makes
 sense to use the public `term_id` as the "owner" of termmeta.
 `term_taxonomy_id` thus becomes deprecated. (It could just as well be the
 other way around, though then we need a translation layer.)
 - We'll need CRUD wrappers for `add_metadata()`, `update_metadata()`, etc.
 - `meta_query` support for `get_terms()` and maybe other term-fetching
 functions.
