 I'm going to close this out as a `wontfix`.

 I do not think Core should make assumptions about what post meta is "no
 longer being used".
 - There is currently no way to tell when post meta is updated or utilized.
 - It's not uncommon for post meta to be set once and never change.
 - If meta remains after using `wp_delete_post()` (or remains "orphaned",
 in general), then we should look into why this happens and fix it.
 - If a plugin, theme, or custom code is using a direct query to remove a
 post, then they should be educated on the benefits of using

 Expired session data stored in transients, as referenced in the
 description, is a much different use case. Transients have an explicit
 expiration timestamp that defines when data should no longer be used.
