What if rather than creating a process that loops through every single post trying to cleanup old orphaned meta values, the plugin instead cleaned up values no longer in use when the post was edited/saved?
This wouldn’t give you the 1 click solution but, it would cause the database to clean and improve itself over time.
Has any new DB optimization plugin been created since the inception of this question that is capable of cleaning up these meta values? I assume not since the values aren’t orphaned… right?
