 > You mentioned somewhere about writing out a guide on how you'd do this
 for core if implemented. Did you ever get around to that? I'd just like to
 future-proof some stuff I'm working on as much as possible.

 I didn't, mainly because after a few conversations we couldn't come up
 with a good way to do this for core.

 As described in #17477, we don't pass around term_taxonomy_id in our API,
 but rather term_id, which requires one to also pass around the taxonomy
 argument. For a meta table, ideally we'd want just one key (thus
 term_taxonomy_id) rather than two (term_id, taxonomy) but our current
 taxonomy API doesn't really allow for that (and our metadata API doesn't
 allow for the other). So I don't think this can happen in core until our
 API grows further.

 There are three plugins in the directory [1]. IIRC, one uses
 term_taxonomy_id, one uses term_id (alone), one uses term_id + taxonomy.
 They seem to use different terminology for either function names, field
 names, or table names.
