Comment (by peterwilsoncc):

 The function has been renamed to `_prime_post_parent_id_caches()` in
 [56811] to ensure it gets in to the beta scheduled 24ish hours from now.

 Still under discussion:

 * Priming the post parent on save, see [https://github.com/WordPress
 /wordpress-develop/pull/5443 PR #5443]
 * Whether to move the cache to the `posts` group to ensure the new caches
 are cleared as part of a call to `wp_cache_flush_group( 'posts' )` -- the
 cache key would require either a prefix or a suffix, see WIP
