Comment:

 Introduced in [45357] / #46937

 `upgrade-core.php` runs in the context of the previous WordPress version,
 any function calls to almost any function added after it was introduced
 need to be checked via `function_exists()`.

 In addition to the mention `wp_get_update_php_annotation()`,
 `wp_get_update_php_url()` (WP 5.1) will also need checking.
