Comment (by ryan):

 Before removing vars, we need to make sure wp-admin/includes/upgrade.php
 doesn't use them.  upgrade needs to concatenate $wpdb->prefix with the
 table name for the removed tables.  We might want to set the table vars in
 wpdb to something like "categories_is_gone" instead of removing them so
 that an obvious error is generated when those tables are referenced.
