Comment (by dd32):

 I feel like there's another ticket for this, however, I'm wondering if the
 following will both work with the intended purpose of this code and work
 with modern MySQL/PHP:

 `$wpdb->query( $wpdb->prepare( "SELECT %s AS $prefix", $prefix ) )`

 This check is to validate that the database prefix chosen is viable on the
 MySQL variant unquoted, ie. "Can I query for '{$prefix}posts' or would I
 need to escape characters in the $prefix for it to work".
