 As an API `get_page_by_title()` is somewhat problematic in that it can
 return a post with a post status that may not be visible to the current
 user, potentially leading to 404.

 It is also somewhat flakey in that a change in post title within the admin
 will potentially break a site using it to return a particular post.

 Additionally, the lack of `orderby` clause results in undefined behavior
 at a database level: different database engines and versions optimize the
 query differently and return results using different indexes. (This
 changed in 6.1 but is likely to be returned in 6.1.1 due to #57039).

 I propose the function be deprecated in 6.2 as an API and developers
 recommended to use `WP_Query` directly in the event they need to get a
 post object by title.
