Yes, PLEASE have editors test it out before forcing it on wikis. Dream Fiction Wiki (one of the sites i admin) depends on infoboxes and now the template system is super hard to use in UCP. And they didn't think about migrating the sister wiki instead, which only depends on headings, image, and very few templates.
