Comment(by aaroncampbell):

 I can't seem to get this to work.  It seems that at line 1392 of wp-
 include/query.php `$this->meta_query` is always empty (doesn't seem to get
 filled form `$qv`).

 Also, `wp_array_slice_assoc()` uses isset instead of empty, and since
 `meta_key` and `meta_value` are always set you always get an empty set
 attached.  It seems like the best solution would be to remove `meta_key`
 and `meta_value` from `$keys` in `fill_query_vars()`.  I'll look at the
 other places it's used, but it might also be possible to use !empty
 instead of isset and this part would be fixed.

 I fixed these, but it's currently all mixed up with my patch for #9124.
 I'll separate them and attach them to their respective tickets soon.
