 4.8.2 specifically restricts the very convenient usage of %1$s, %1$d, %1%f
 placeholders in WPDB::prepare. For yet undisclosed security purposes.

 Since this has been very widely used in code as an undocumented feature, I
 propose to bring it back, provide official support and documentation for
 it.

 https://github.com/search?q=wpdb-%3Eprepare+%251%24s&type=Code&utf8=%E2%9C%93
 over 1.2 million search results using the no longer supported syntax.
 Including the very popular Yoast SEO plugin which broke unexpectedly with
 the recent security update.
