Comment:

 In [changeset:"27689"]:
 {{{
 #!CommitTicketReference repository="" revision="27689"
 When using `meta_query` in a `WP_Query`, passing `NOT EXISTS` or `''` to
 `compare` should not require `value` to be set. The resulting SQL should
 then produce the appropriate `OR` clause for existence of non-existence
 after passing the query to the `$key_only_queries` stack internally.

 Adds unit tests.

 Props chrisguitarguy, for the original patch.
 Fixes #23268.
