:The normal way to describe the "text" of an opera is its "libretto", and its writer as the "librettist". So no, I don't think that's an improvement. I don't consider listing the native and translated titles (if they have a standard English translation) unnecessary. Nor do I consider the language of the libretto to be redundant. If you want to suggest improvements/changes to this template in general, then you should join the current discussion at Template talk:Infobox opera. The page also documents the prior discussion and suggestions from several editors when the template was being developed. Note also that Gerda is not restricted from editing existing infobox templates, and the change was a very minor update.
