Comment (by jtsternberg):

 So, why are we introducing yet another global, `$wp_meta_keys`, instead of
 using a registry class of some sort?

 A registry with some kind of `register`/`get`/`check`/`has_collision`,
 etc, would be hugely beneficial IMO, and we can keep the array protected.
 Also protects some of the workings of the internal API as we can keep the
 methods protected, which means we won't have as much back-compat to worry
 about as we progress with the `register_meta` api.
