Roadmap for the post and term locales proposal

Here’s what I feel we need to do to investigate the proposal to add locales to posts and terms, and to test whether this is feasible and desirable.

Write a proof of concept plugin which:

  • Implements a new column in wp_posts and wp_terms
  • Implements an enhancement to WP_Query

Then test this against some existing multilingual and non-multilingual plugins, looking for:

  • Performance
  • Any bugs or unexpected behaviours introduced

I also think it would be good to look at how locale information for posts and terms might be exposed via the proposed WordPress REST API endpoints (I knowledge or preconceptions here).

I’m happy to have help on this journey.
