-----------------------------+----------------------------
 The `_wp_delete_all_temp_backups()` function returns a `WP_Error` object
 when there's a failure condition, but this function is only used as a cron
 event callback function so the return value is not used anywhere.

 As core has no error handling for cron events, I recommend triggering an
 error for these conditions (probably via `wp_trigger_error()`) and then
 doing early returns so the function returns void.
