As per https://drupal.org/node/2281933, using l() in hook_views_data_alter() may cause breaking site. Taking into account amount of tickets open for Views, this issue can take a long time to fix. Meanwhile it's quite easy to avoid it for search_api_elasticsearch module by just replacing l() with <a> tag (though it's not drupal way).
