Comment (by desrosj):

 In [changeset:"46205" 46205]:
 {{{
 #!CommitTicketReference repository="" revision="46205"
 Code Modernization: Deprecate the `Services_JSON` and
 `Services_JSON_Error` classes.

 The PHP native JSON extension has been bundled and compiled with PHP by
 default since version 5.2.0. Because the minimum version of PHP required
 by WordPress is now 5.6.20 (see #46594 and [45058]), JSON extension
 related polyfills and backwards compatibility code can now be removed.

 Since there are still some plugins and themes that utilize the
 `Services_JSON` class, these classes will remain for the time being, but
 including the `wp-includes/class-json.php` file and creating
 `Services_JSON` instances will now throw deprecated notices.

 See #47699.
