	 * Backward compatibility, where wpdb::prepare() has not quoted formatted/argnum placeholders.

	 *     $wpdb->prepare( 'WHERE `%1$s` = "%2$s something %3$s" OR %1$s = "%4$-10s"', 'field_1', 'a', 'b', 'c' );

	 * But it's risky, e.g. forgetting to add quotes, resulting in SQL Injection vulnerabilities:
	 *
	 *     $wpdb->prepare( 'WHERE (id = %1s) OR (id = %2$s)', $_GET['id'], $_GET['id'] ); // ?id=id
	 *
	 * This feature is preserved while plugin authors update their code to use safer approaches:

	 *
	 *     $wpdb->prepare( 'WHERE %i = %s',         $_GET['key'], $_GET['value'] ); // WHERE `a``b` = 'value'
	 *
	 * While changing to false will be fine for queries not using formatted/argnum placeholders,
	 * any remaining cases are most likely going to result in SQL errors (good, in a way):
	 *
	 *     $wpdb->prepare( 'WHERE %1$s = "%2$-10s"', 'my_field', 'my_value' );
	 *     true  = WHERE my_field = "my_value  "

	 *
	 *     $wpdb->prepare( 'WHERE id = %1$s', $_GET['id'] ); // ?id=id

	 * Note: There is one exception to the above: for compatibility with old behavior,
	 * numbered or formatted string placeholders (eg, `%1$s`, `%5s`) will not have quotes
	 * added by this function, so should be passed with appropriate quotes around them.
	 *
	 * Literal percentage signs (`%`) in the query string must be written as `%%`. Percentage wildcards
	 * (for example, to use in LIKE syntax) must be passed via a substitution argument containing
	 * the complete LIKE string, these cannot be inserted directly in the query string.
	 * Also see wpdb::esc_like().
	 *
	 * Arguments may be passed as individual arguments to the method, or as a single array
	 * containing all arguments. A combination of the two is not supported.

	 *
	 *     $wpdb->prepare(
	 *         "SELECT * FROM `table` WHERE `column` = %s AND `field` = %d OR `other_field` LIKE %s",

	 *         "SELECT DATE_FORMAT(`field`, '%%c') FROM `table` WHERE `column` = %s",
	 *         'foo'
	 *     );
	 *
	 * @since 2.3.0
	 * @since 5.3.0 Formalized the existing and already documented `...$args` parameter
	 *              by updating the function signature. The second parameter was changed
	 *              from `$args` to `...$args`.
	 * @since 6.2.0 Added `%i` for identifiers, e.g. table or field names.
	 *              Check support via `wpdb::has_cap( 'identifier_placeholders' )`.
	 *              This preserves compatibility with `sprintf()`, as the C version uses
