 I don't mean for //all// post meta additions and updates. I mean
 specifically in `WP_Sync_Post_Meta_Storage::set_awareness_state()` and
 `WP_Sync_Post_Meta_Storage::add_update()`.

 Here's what I have in mind: https://github.com/WordPress/wordpress-
 develop/pull/11002

 The only post meta involved would be `wp_sync_awareness` and
 `wp_sync_update`. I don't believe there are any queries introduced which
 involve querying by these post meta.
