Comment (by peterwilsoncc):

 I think the filter in the proposed patch is good but the docblock
 improvements:

 > Filters the attachment ID to allow short-circuit the function.
 >
 > Allows plugins to short-circuit attachment ID lookups. Plugins making
 use of this function should return:
 > - 0 (integer) to indicate the attachment is not found
 > - attachment ID (integer) to indicate the attachment ID found
 > - null to indicate WordPress should proceed with the lookup.
 >
 > Warning: The post ID may be null or zero, both of which cast to a
 boolean false. For information about casting to booleans see the {@link
 https://www.php.net/manual/en/language.types.boolean.php PHP
 documentation}. Use the `===` operator for testing the post ID when
 developing filters using this hook.
 >
 > @param int|null $post_id The result of the post ID lookup. Null to
 indicate no lookup has been attempted.
 > @param string $url The URL being looked up.
